Catalase is an enzyme, which is present in potato's it breaks down Hydrogen peroxide in to Water and Oxygen. Enzymes are biological catalysts. An enzyme is protein that acts as a catalyst in biochemical reactions. Each enzyme is specific to a particular reaction or group of similar reactions. Enzyme activity is influenced by substrate concentration and by temperature and pH, which must lie within a certain range. Catalyst speed up a chemical reaction by finding an alternate route where the experiment can go throw.

Enzymes control all metabolic reaction. Enzymes are present everywhere in human bodies, washing powders, rivers and the production of fruit juice. Catalase is found in almost any kin of living cells. The reason why Catalase is present in living

If there were more catalyse the reaction would react faster. This is because there will be more Catalase to react with.
