Catalase By Andy Mc Namee The effect of surface area on the activity of catalase in potatoes Planning: *Hypothesis* hydrogen peroxide will breakdown to oxygen and water in the presence of Catalase. The reaction will increase with increasing enzyme concentration when molecules of hydrogen peroxide are freely available. However, when molecules of the substrate are in short supply, the increase in rate of reaction is limited and will have little effect. Enzymes are globular protein biological catalysts; it is called a catalyst because it helps speed up chemical reactions. As enzymes are globular, this means that they are coiled up into a 3-dimensional shape they have hydrophilic side chains on the outside to ensure that they are soluble.
