Enzymes- reduce the amount of energy required for the reactions they catalyse [accelerate]. -thus‚ increasing the rate of reactions that occur in living organisms. WITHOUT enzymes : metabolism would be so slow at body temp. that insufficient energy would be available to sustain life. -Many enzymes are “Intracellular”- used within the cell that produced them e.g. enzymes in respiration & photosynthesis -Others are “extracellular”-they act outside the

the outcome of enzyme activity Introduction In this project I will monitor the rate of activity of Catalase. Catalase is an Enzyme which in the right conditions catalyses the decomposition of Hydrogen Peroxide into water and oxygen; 2H2O2 + Catalase >>> 2H2O + O2 Catalase is found in all cells and protects them from Hydrogen Peroxide which is a dangerous waste product that needs to be eliminated. Without Catalase living things could not survive. What are Enzymes? Enzymes are found in the

The American Revolution was an extremely important event in history; social‚ political and economic aspects all helped develop a very strong revolutionary spirit within the colonists of America. It helped enlightenment philosophers like John Locke or Benjamin Franklin to step up and lead the revolution politically with great success. All these aspects made the American Revolution the historical landmark that it is today; it symbolizes the way that Americans came together to become independent and

stamped electronically‚ almost all documents are produced on CDs or DVDs‚ and our photographs and videos are stored digitally. Getting there has been easier and much more successful than we expected. In retrospect‚ one of the smart things we did was to introduce only one new element of technology at a time‚ which enabled us to avoid trying to learn several new pieces of complex software and/or approaches at once and mastering none. The first step occurred in 2001‚ when we purchased and installed

He was so good he almost seemed too good. Even the king admired Macbeth‚ saying‚ “O valiant cousin! Worthy gentleman!” (I ii 24) and “My worthy Cawdor!‚“ (I iv 48) agreeing with how amazing Macbeth is. Many believed there was a lot more that Macbeth could have achieved‚ had he not fallen from grace. Macbeth was a great person‚ and the person he later became was not the same wholesome character. Macbeth was once a great person and this made the story of

The Erie Canal‚ or the Great Western Canal as it was initially known‚ was one of the most important state projects of the early years of the United States. It proved to be overwhelmingly succcessful and its success prompted other state economic development projects. Before the Erie Canal was built New York City was not the premier port of the United States that it became. Philadelphia was the largest‚ most prosperous city of the new United States. The Erie Canal provided the base for New York City’s

People from all sorts of different social‚ and racial groups took a stand for what kind of reforms they believed in‚ and once their following grew big enough‚ they were able to be heard.

Chirag Patel Biology 157 Determining the Effect of Varying Substrate Concentration Question: How does concentration of potatoes affect the amount of oxygen produced with hydrogen peroxide and potatoes (enzymes)? Introduction The enzyme used for this experiment is Catalase. Catalase is inside mostly any living organism which uses oxygen. Its job is to break down hydrogen peroxide‚ into oxygen and water. (Formula) 2H2O2 ---> 2H2O + O2 (lab manual). There are limiting factors which if altered

The Progressive Era is well known for reform‚ change and making America better. Order‚ structure‚ control‚ and the betterment of were some motives for progressive reform. While the population was calling for reform it was the responsibility of the government to reform society. Separate Car Acts‚ Plessey v. Ferguson and The Jim Crow laws are some of those reforms that government put in place to help make America more American and protect the people from the ‘outsiders’. These reforms can be considered

Write a balanced chemical equation with state symbols for the reaction catalyzed by peroxidase. 2H2O2 2H2O + O2 (4H1 4O) (4H + 2O + 2O) 2. What is the substrate(s) of this reaction? What is the catalyst? Substrate = H2O2 hydrogen peroxide Catalyst = peroxide 3. At what approximate temperature do enzymes normally operate in the body of a warm-blooded animal? Would your answer change if the enzyme came from a plant or yeast? Enzymes normally
