Enzyme are catalytic proteins whose purpose and function is to accelerate reactions by lowering the activation energy. Enzyme only allows certain reactants to bond with it. In this lab you will be able to see the reactants as it bond with the enzyme. The laboratory method used in this experiment was basics. How fast can the Enzyme move through to produce? In the lab we are going to use Hydrogen peroxide and enzyme catalase and water, the catalase is used to break down the Hydrogen peroxide and the oxygen in the water. You will be able to see as the oxygen produce in the reaction chamber and travel through the hose and up the graduated cylinder. We are going to capture the oxygen gas that being produce in the reaction chamber and see how…show more content…
Nearly all living things possess catalase, including us! This enzyme, like many others, aids in the decomposition of one substance into another. Catalase decomposes, or breaks down, hydrogen peroxide into water and oxygen. The substrate, undergoes a chemical change – the new substance is released from the active site. The active site springs back to its original shape and is ready to receive fresh substrate. For enzymes to operate they must be able to make contact with the substrate; the enzyme or substrate or both must be in solution. Our cells are about 90% water and water is the medium in which most of our biochemistry takes place. The value shows that there is a positive correlation between the rate of reaction and hydrogen peroxide concentration. Catalase, or enzymes, drastically increases the rate of hydrogen peroxide decomposition. This lab shows how catalase added to hydrogen peroxide leads to the release of oxygen, if hydrogen peroxide was required to decompose naturally, life could not survive. The addition of catalase increases this decomposition rate allowing life to continue. For enzymes to operate they must be able to make contact with the substrate; the enzyme or substrate or both must
