Lab report on enzyme activity. Essay Example

Lab report on enzyme activity. Paper The reactant an enzyme acts on is referred to the enzymes substrate. The enzyme will combine with or to its substrate. While the two are joined, the substrate is converted to its product by catalytic action of the enzyme. There is an active site of the enzyme molecule which is a restricted region that actually attaches to the substrate. Usually the active site is formed by only a few of the enzymes amino acids, the rest is just the framework that reinforces the active site. In an enzymatic reaction, the substrate enters the active site then is held in place by weak bonds. Now the enzyme does its work and first changes shape so it can hold onto the substrate. Next the substrate is changed to its product, the product is released and the enzymes active site is ready and waiting for another molecule of substrate. Amylase is an enzyme in human saliva and in other organisms and its substrate is starch. When the active site of amylase binds with the starch, hydrolysis takes place. When the hydrolysis (the breaking of a chemical bond with the insertion of the ions of a water molecule) of starch is complete you are left with a saccharine called maltose.

METHOD To prepare for the experiment the following equipment was assembled: a spot plate, a test tube with amylase and starch in it, a Pasteur pipette, and iodine. The spot plate was labeled in time intervals each two minutes apart. A drop of iodine was placed in each area of the spot plate. This will demonstrate how long it takes the amylase to hydrology the starch. Using the pipette, a drop or two of the amylase/starch mixture was placed in one circle containing iodine on the spot plate. If the iodine turned blue, the hydrolysis is incomplete and the test was repeated at two minute intervals. If it remains the color of iodine the reaction is complete. The time that elapsed from the beginning of the the reaction is noted. To test the affect of temperature differences on the reaction 4 test tubes with a starch/amylase mixture were labeled at different degrees C. C, ICC, ICC, ICC. The test tubes were immersed in 4 water baths that were at the temperature babbled on the test tubes. The test tubes were left immersed for 10 minutes. The procedure noted above with iodine was followed for each test tube and the results documented. To test the effect of pH on the rate of hydrolysis 4 buffered solutions of pH 1. 0, 3. 0,7. 0 and 10. 0 were prepared . 4 test tubes were labeled with the different pH levels. The appropriate buffer solution was added to each test tube. Next . 5 ml of amylase was added to each test tube. The test tubes were plugged and inverted to mix the contents. Beginning with the test tube with lowest pH, 10 ml of starch as added to each tube. The tubes were again plugged and inverted to mix the contents. Again the procedure with the iodine was followed and the results documented. To test the effect substrate has on the rate of hydrolysis 4 test tubes were labeled with the following substrate dilutions: 50%, 25%, 10% and 5%. In the 4 test tubes, the following starch solutions were prepared: Dilution Starch Water Ion-II Ion-II ml ml ml ml 5% Mil ml . 1 ml of amylase was added to each test tube and the procedure with the iodine was followed and the results documented. To test the effect of enzyme concentration on hydrolysis, 4 test tubes were labeled with the following enzyme dilutions: 5%, 2. 5%, 1%, . 5%. In the 4 test tubes, the following enzyme solutions were prepared: Dilution Amylase Water 5% 2. Mm 0. Ml 2. 5% I. Mol I. Mol 1% . Ml 1. Ml . Mi 1. Ml Then ml of starch to each tube, the procedure with the iodine was followed and the results documented. RESULTS Upon the conclusion of the test, it was determined that variances of temperature, pH, substrate and enzyme concentration did affect the rate of he reaction. Different than what a person may think, the rate of reaction was longer with the colder temperature and the highest temperature. The rate if reaction shortened with the middle temperatures of 24 and 40 degrees C. In the test of the pH variances, again the results showed the longest rate of reaction in the highest and lowest pH levels. The rate of reaction decreased when the pH level changed from 3. 0 to 7. 0. The substrate concentration variances showed a steady increase in the rate of reaction in relation to increase of concentration. The enzyme concentration showed a steady decrease in the rate of reaction in relation to increased concentration. All raw data is stated in graphs at the end of this report. CONCLUSION It was confirmed in this experiment that changes in the environment like temperature, pH levels, substrate and enzyme concentrations did effect the rate of reaction. It really should be evident that the substrate and enzyme concentration levels would effect the rate of reaction the was they did as it was noted in the intro of the paper the role each one of these plays in the reaction process.

Free Essays on Matisse Picasso

The world Matisse and Picasso existed in was one of intense competition. Each strived to maintain their own personal style while simultaneously adapting to their surroundings. â€Å"To take possession is also to confess to indebtedness(Bois).† Their group and personal exhibitions were a vehicle to expose themselves to the rest of the art world and to eachother. However, they also felt the need to reciprocate ideas and attain a further understanding in studies of space, divisions of composition, and their differing views of models back and forth between themselves.

Second Home - Essay Example Specifically, the author’s diction, her sentence structure, the choice of words, imagery, and figurative language are important aspects of the use of tone. One of the key techniques employed by the writer is the use of imagery in expressing the mood of the essay. The author is extravagant in painting images and visual aspects of the places that she describes in the minds of the readers. This use of image shapes the general idea of the subject in the mind of the reader by portraying it as either negative or negative. For instance, the writer clearly shows that she is lonely in saying that â€Å"in general, I get a huge amount of pleasure out of filling my home with the things that other people used to have in theirs. What more can I say?† The writer further portrays herself as a nonsocial being using aspects of imagery. It is, in fact, the reason why she constantly remembers her childhood and seeks comfort in personifying objects. â€Å"I had a nice phone conversation with the woman who runs the store and ordered two dolls from her store, both young ladies, thinking it would be awesome if my family was made up of two grown siblin gs living together.† The writer further explores figurative language in shaping the feelings of the reader. For example, the writer states that â€Å"I had a revival of interest in my dollhouse when I was around 11.† This statement goes to show that she was reminiscing about her childhood and missing it. The same technique is used in her later life as she remembers her dollhouse to remember her childhood. The writer uses the scale of 1:12 to show the importance of making a good dollhouse. She says that â€Å"one inch representing one foot in a real room†. Moreover, the writer personifies the dolls towards the end of the essay by calling them Lily and Hyacinth. The author uses her word diction to portray the mood of the essay by changing between formal and ordinary levels.

Biases and Judgments Essay Example | Topics and Well Written Essays - 250 words

Biases and Judgments - Essay Example The decision entailed reflection aimed at enhancing the progress of the organization and improve performance. These decisions also promote efficiency in the staff and management. This decision could act as the basis of action since the policies could be implemented (Salaman, 2001). Emotions can influence the decisions that the management of an enterprise makes. Emotions can affect rational decision making; those who follow emotions make irrational decisions. As such, businesses should not come up with decisions based on emotionality as the decisions, may have a negative impact. Fairness should prevail while making decisions; all departments within an organization should be treated equally (Yates, 2003). According to Salaman (2001), reflective decision making includes examination, contemplation, critical meditation and analytical thoughts when making decisions. Therefore, reflective decision makers ensure that managers critically analyze the decisions they make. Reflection means that the decisions have to be given a deep thought before implementation; implementers take their time before coming up with the decision. On the other hand, expedient decision making entails solving problems that require immediate solutions. Expedient decisions mainly stem from the need for them; business organizations mainly make them when need to do so arise. For example, an organization may decide to lay off employees instantly. Yates (2003) asserts that biases may arise when making decisions; they include dependency on one form of information where decisions makers tend to over rely on one course of action. Other biases may include overconfidence on the decisions made and selective gathering of informat ion. Thus, in conclusion, the essay has discussed business decision making. It has addressed the role of decision making, which enhances progress in a business. Emotions and biases have a negative impact on the decisions made; they may lead to poor

Online bidding Essay Example for Free

Online bidding Essay E-bay means you can search for items on the internet through its search tool bar. To access E-bay you go on www. ebay. co. uk here you can search for items you may want or need using the search tool bar and typing in key words. This will then bring up matching items that other people have put on e-bay to sell. From here you can view prices, details on the items and many have images for you to view the product. If you have found something you would like to bid for you put in your bid. When the time period for that item on sale ends, usually one week the person that has put in the highest bid for it gets it for that amount. However the seller can put on a reserve, if the reserve is not met the seller does not have to sell. Payments can be made by credit card or by sending a cheque in the post. Pay pal is the most popular way of paying for goods as it is well protected and secure. Goods are then posted or shipped out to the highest bidder. It is open to the whole world and you can therefore purchase things from other countries like China or America. You can purchase anything from kids toys to cars on eBay. One of the things that more and more people are buying on ebay is holidays. Some advantages of using online auctioning are; firstly you can shop on the internet from the comfort of your own home. This is a lot more relaxing, saves energy and time having to go in and out of shops. Another is that on ebay you can search for virtually anything and find what you need for example if you want to buy a perfume, a new handbag and look around for a new car you can look for all of these on one site. If you were to go out looking for these if would mean a lot of walking and travelling as there is not a shop that does al these. Another advantage of shopping on ebay is that you get special online prices; prices on ebay are usually a lot cheaper than in shops. Ebay alerts are useful as it emails you if your bids have been successful or if they have been out bid. Disadvantages of using online auctioning are; credit card fraud. One of the main things that put people of bidding for items online is that credit card fraud is a risk they will have to take, as there are many hackers out their who can brake the best security codes. Another disadvantage is that you have to keep checking the status of your bid because some one may have out bid you and you will then not get the product unless you out bid them. You also have to wait for what you have bought. Firstly you have to wait for the payment to go through which may take a few days and then you have to wait for it in the mail, depending on how far you have ordered from and the conditions arranged with the seller you cloud wait a very long time or a really short time for your products. Another disadvantage is that you do not know who the seller is and although the auctioning company will have their details people can still get away with fraud by taking payments and not sending anything out. Also faulty items can be a pain, if you product is not working properly or at all you have to send the goods back to the seller and then claim money back. This can turn into a very long process and can lead to court if it turns into disputes as the seller can claim it was working and refuse to refund. I think the target audience for online auctioning is for older people from about the age of 20 and upwards to about age 45. I think this because you need a credit card to be able to auction therefore you will need to be over the age of 18. I think male and females will use it, I also think more people without children will use it as you will need time to sit and search, with children this may be difficult. To auction online you will need to register with a credit card. If you do not have a credit card you will not be able to do it. Once register you can bid but also sell your own items.

Roman Gladiators Essay examples -- Roman History

Gladiator Gladiatorial events were a token of the Roman civilization. A brutal form of sacrifice adapted from the earlier civilization of Etruscans, who believed when a person dies, his spirit relies on a blood sacrifice to survive in the afterlife. The first event to take place in Rome was in 264 BC, when Decimus Brutus held a sacrifice to honor his dead father (Roman Gladiator). Soon after these events became an undeniable part of the Romans lives, used for political power and general entertainment. A gladiators life was far from easy. Most were slaves, prisoners of war, or hardened criminals, therefore they were not free men. Often times they were trained and forced to take part in the events, hoping for their freedom if they were to conquer their grim fate and survived for a few years (wik). This was depicted in the most recent movie GLADIATOR. In this film Russel Crowe ‘Maximus' starts out as an army general under Marcus Aurelius, until Commudus murders his own father out of spite for his fathers loyalty to Maximus and not him. He then inherits the title of king, and condemns Maximus to a gruesome fate as a slave/gladiator. Though this doesn't sound like the ideal life, to some at the time is was an appealing, so much so that some free men degraded themselves so they could battle in the games. Was it for basic living? Possibly but more than likely it was for the Fame and Prestige of a Gladiator. These free men were known as Professional gladiators. Training was hard for these great warriors, they often trained at special gladiator schools, the largest of which was connected to the great Coliseum by underground passages. Here they learned how to fight skillfully with swords, daggers, nets, chains, and an... ...m. This huge circular arena was the pinnacle of the Roman Gladiatorial games, and though it isn't fully intact, it is a great reminder of ancient culture. Though today these games seem inhumane and unnecessary, to their ancient culture it was a vacation from everyday stress. Even the Emperor was said to understand that though money and grain would satisfy and individual, large spectacles were necessary for the ‘contentment of the masses' (wes civ). Works Cited 1.

He was born into a family of computer experts. His father was a pioneer in artificial in telligence and computer science and is mother a computer programing teacher. He grew up in a house where technology was the norm, computers parts and Popular Mechanics magazines where everywhere.His older brother taught him from early on how to disarm artifacts in order to find out how they worked, this fueled his knowledge and motivation greatly to begin inventing, he once built a working inkjet printer out of LEGOS, at age twelve Page already knew he was going to have a company eventually. Page was first attended the University of Michigan for a bachelor’s degree in Engineering and then decided to pursue a master’s degree in computer science at the Stanford University, here is where he met Sergey Brin and started the project that would change his life forever.The idea began while searching a dissertation theme about exploring the mathematical properties of the World Wide Web. According to John Battelle, founder of â€Å"Wired† magazine page assumed that web li nks where just citations so his project named â€Å"Backrub† was about classifying and counting all the backlinks of the World Wide Web and according to Page it would make it a more valuable place. At the beginning of â€Å"Backrub† the World Wide Web could be sought as a giant book without an index, so the goal of the project was to gather data and index it using what is called a web crawler, a bot programmed to perform this specific task.Then Page and Brin created their first product called â€Å"Pagerank† which was an algorithm that assigned numerical weighting to the hyperlinks already indexed by the web crawler and measure its importance, from here he created a search engine that was far more effective than the ones that already existed. This new Google search engine made its first debut at the Stanford University webpage in 1996. Together with is partner Brin in 1998 he founded Google Inc. at the time he hired Eric Schmidt as a CEO.The company’s mis sion was â€Å"To organize the World’s Information and to make it universally useful and accessible. † In 2006 the company was already made public and had its main quarter in Mountain view, California. Google Inc. grew very quickly and began to add more products and services such as email, advertising services, location services, productivity software and photo editing software and much more other breakthrough and innovative services and products just as the Android mobile operating system and Google Chrome Browser. Today Google. om is listed as the internet most visited website in the U. S according to Alexa Traffic Rank. And many of its famous brands are in the top hundred most visited sites such as YouTube and Blogger. According to an article by the social media online magazine Mashable, Google reported earnings of 50 billion dollars in January 2013 and is still expanding. Decoding Larry Page Leadership Style Because of his decision of hiring Eric Schmidt as CEO bac k in 2001 Larry Page was often cataloged as an introvert leader and when he took back the title of CEO in 2011 he didn’t hold any big meetings, interviews.What matters the most to Page is innovating this can be appreciated by the fact that he spends $1 billion on patents to help the company grow, this was sought to emulate Steve Job’s leadership but the truth is that this is most likely shaped by his engineering background. According to an article by CNN Money he still remains an enigma and his leadership style can be appreciated during commencement speeches and talks to coworkers and Google executives.During these talks he focuses about the future, as stated before Page is all about innovations and he firmly believes that by tackling audacious ideas that can eventually change the world would attract incredibly smart people that can achieve something worthwhile as he expressed at the Google Faculty Summit in 2009. Page’s supportive leadership style can be proved by his proficiency at building networks and expertise building and leading teams. He insisted on being very closely involved in the hiring process at Google always looking for university graduates to join the company.It is widely known that he dislikes the traditional bureaucracy and management styles and is always cutting or reassigning middle management positions. This can be seen by the company’s reorganization tendencies. While studying the company’s website it can be seen that all the description and pertinent information is compressed to no more than one paragraph, this is because Page encourages faster and concise decision making. According to wall Street Journal he would ask managers to e-mail him updates of their projects in 60 words or less.Also he encouraged them to have a session in the afternoon where top executives had to work on a public area of the building in order to make them more accessible to employees and facilitate communication among each other . This shows very strong supportive and participative leadership styles. Because the company is not organized with the typical management styles and is more focused on projects a team environment is the rule here which encourages involvement of followers in every aspect of decision making processes.Although he involves the team when it comes to decision making within a project he displays directive leadership traits when it comes to organizing the company. According to Google board member Mr. Ram Shriram he has a very clear idea of how the company should be organize therefore he personally picked the people that could run large areas of the company and set their objectives. Page would set very clear-short term and long-term goals for his managers. After further research it is very clear that Larry Page’s strongest leadership styles are participative and supportive.According to an interview by The Fortune magazine the wellbeing and lifestyle of the company’s employees i s top priority to him as he says â€Å"My job as a leader is to make sure everybody in the company has great opportunities, and that they feel they're having a meaningful impact and are contributing to the good of society. † Google is known for its innovative work space that are far from looking like a typical office, he feels that the company is like a family and therefore he treats them like one.This has boosted employee satisfaction, productivity and even improved their health to the point that their healthcare costs grow less compared to other companies. As stated before Page is regarded as an introvert, which might contradict the traditional believe that a leader should be outgoing and charismatic in order to be successful but the fact that he is an introvert supplies him with other set of traits and skills that make him successful and ultimately explain his supportive and participative tendencies.Traits that characterize introverts are that they are very good at listeni ng; therefore they are not going to dominate a social situation which will allow them to hear about other people’s innovative ideas. This will also explain Page’s tendency to want to attract people qualified as intelligent. A person that has an engineering and technologic mindset would rather hear from a smart person than a charismatic one. In addition Page has a strong directive approach when it comes to setting the company’s main goals but he is willing to let his followers choose their path to reach those goals.Nevertheless Larry Page has been a CEO for a relatively short amount of time so there is still a lot to see from this leader. During his short time as a CEO he has definitely demonstrated strong organizational skills and has brought back cohesion and focus as well as decisiveness to a company that was becoming scattered within is many diverse projects. Larry Page’s Leadership Style Applied to Hospitality Industry Google’s innovative appro ach can bring great success for someone working in the hospitality industry.The hospitality environment is all about communication and team work, this is a people’s business therefore it is imperative to have a supportive approach when leading followers. There are many levels or work in this industry that range from skilled labor to management and business work. Page’s supportive approach can be very beneficial for hotel managers because they are leading people that come from all sorts of backgrounds, by providing an environment where the employees feel comforted and supported by their company it will increase employee’s satisfaction and productivity at their workplace.For example a manager can display this kind of behavior if a front desk employee becomes frustrated with a hard situation involving a difficult guest or is having some kind of hardship in their personal life a manager can encourage communication with the employee and provide an understanding attit ude as well as build a better relationship with the employee that will allow that employee to feel comfortable within his workplace augmenting their feelings of empowerment and therefore excelling at their duties.The hospitality industry environment requires critical thinking skills, our industries workspaces are the same but a day and a situation is never the same, a hospitality employee have knew experiences and new interactions everyday with customers. Participative behavior from managers is extremely important; a manager cannot be in every place at the same time. Every employee has different experience at the workplace due to the nature of the Hospitality industry, for example a front desk agent that does the A.M. shift has a completely different experience and needs than the one doing the P. M. shift. Therefore is necessary that the manager gathers input from his employees in order to improve the processes and procedures necessary to solve a particular problem or to improve the workplace experience. Delegatory leadership is also needed in the hospitality industry because it often involves critical decisions to be made from the followers that directly affect the customers.For example when at the front desk an employer needs to be empowered to make decisions and resolve certain type of problems that might rise like room changes or extra amenities to compensate for ant dissatisfactory experience a customer might have. How Larry Page’s Leadership Styles relate to my mine After analyzing Page’s leadership traits I found myself very related to his style. As a leader I see myself revolutionizing the workplace, giving a lot of importance to the way an employee is treated and feels after analyzing Page’s leadership traits I found myself very related to his style.As a leader I see myself revolutionizing the workplace, giving a lot of importance to the way an employee is treated and feels while doing his work. The challenges that might be found applying his style to the type of career I am doing would be overcoming an industry that is already established and has a bureaucratic management style, it would be a groundbreaking task to apply a more relaxed and creative work environment and involve the employees in the decisions of the company.I strongly believe that innovation and technology can be brought to this industry and can be encompassed with customer experience and this can be achieved if the bureaucratic lines in the current management styles can be blurred somewhat and projects that come from employees ideas instead of only owners of stake holders of a company would take place. Page’s management does not think about money being spent, this is the same vision I have for the hospitality industry.In order to revolutionize the industry and the customer’s experience whether it is by creating new amenities at the already existing facilities or creating new futuristic lodging concepts can only be achieved if t he mindset of making business for money can be put as a second priority. Conclusion My research about Larry Page’s leadership style has been very moving and eye opening. I strongly believe that this should be the management style of the future because he was able to prove that the old bureaucratic style is not necessary in order to make company thrive.The world is constantly changing and therefore the structure of our companies need to change as well and become more proficient and team based in order to reach our full potential as well as innovating and creating new concepts that can be easily achieved by participative leadership and groundbreaking projects.
