Investigating the effect of enzyme concentration on the rate of an enzyme catalysed reaction. Investigating the effect of enzyme concentration on the rate of an enzyme catalysed reaction. Aims: This is an experiment to investigate how the concentration of the substrate Hydrogen Peroxide (H2O2) affects the rate of reaction of the enzyme Catalase, in yeast cells. catalase product The formula: 2H2O2 2H2O + O2 Background information: Enzymes such as catalase are globular protein molecules found in all living cells. They are biological catalysts, and are used to speed up a specific reaction rate within the cell. They reduce the level of activation energy needed in a reaction, which speeds up the rate of a reaction. The higher the activation energy, the slower the reaction will be. The two graphs below show the amounts of activation energy needed with and without an enzyme: All enzymes contain an active site, a depression in the enzyme molecule, where...
