Aim To investigate how temperature affects the rate of reaction of the enzyme catalase on its substrate hydrogen peroxide. Scientific Background Enzymes are biological catalysts which increase the rate of reactions by lowering the activation energy needed for the reaction to tale place. The activation energy is the amount of energy needed for molecules to react when they collide. Molecules need to collide in order to react, this is known as the collision theory. When they collide they may not react as a certain amount of energy is required to break bonds, this energy is the activation energy. Enzymes are made of a long amino acid chain, within this some molecules are attracted to each other, so the chain folds in on itself to form a 3D shape. How enzymes are shaped. An area on the surface of the enzyme is known as the active site. This is where reactions take place to form or break...
