Experiment to investigate the effect of varying surface area hence varying the amounts of Catalase on the breakdown of Hydrogen Peroxide Aim: to investigate the effect of the amount of catalase and the breakdown of hydrogen peroxide. Hypothesis: Hydrogen peroxide will breakdown to oxygen and water in the presence of catalase. The enzyme catalase carries out the following reaction: 2H2O2 2 H2O (l) + O2 (g) Catalase is an enzyme, enzymes are globular proteins that have tertiary structures with hydrophilic R groups that form a precise active site which is substrate specific to hydrogen peroxide substrate. Hydrogen peroxide substrate and the catalase enzyme join to form the enzyme substrate complex. Temporary bonds are formed until the active site of the enzyme splits the toxic substrate hydrogen peroxide into two harmless products, oxygen and water. This process happens naturally but slowly, catalase lowers the activation energy so the reaction happens more quickly without the need...
