An investigation into how the concentration of hydrogen peroxide affects the rate of reaction of the enzyme catalase. Aim The aim of this experiment is to examine how the concentration of hydrogen peroxide (H2O2) affects the rate of reaction on the enzyme catalase. Background Information From previous scientific knowledge I know that catalase is an enzyme found in living cells.It is found in food such as potato and liver. Enzymes are protein molecules and the purpose of enzymes is to speed up reactions, but not be changed or used up during the reaction. Catalase is used for removing hydrogen peroxide from cells. Hydrogen Peroxide is a poisonous product of metabolism, and must be broken down into water and oxygen. Catalase speeds up this decomposition of hydrogen peroxide. Hydrogen Peroxide Oxygen + Water 2H2O2 (aq) O2 (g) + 2H2O (l) It is an Catabolic reaction which means that the hydrogen peroxide molecule is broken down into smaller pieces. The reason this...
