Enzyme Investigation.

... AS Biology Coursework Enzyme Investigation Introduction In this experiment, I will see how the substrate concentration affects the rate of reaction in the break down of hydrogen peroxide, using the enzyme catalase. Hydrogen peroxide breaks down into water and oxygen. This type of reaction, where molecules are broken down into smaller pieces is called an anabolic reaction. Background Information In this experiment, catalase will be used to break down hydrogen peroxide into water and oxygen. Catalase is an enzyme, which is found in every cell in the body. It is a very fast acting enzyme, because it is needed to break down hydrogen peroxide as quickly as possible. 2H2O2 2H2O + O2 Enzymes are a special group of proteins that act as biological catalysts. They are made of proteins, which are made up by amino acids. They speed up the rate of reactions in biochemical reactions (Mr. Nias' notes). Without enzymes, these biochemical reactions in living cells
