An Investigation into the effect of surface area on the activity of catalase in potato In this investigation I will be adding pieces of potato (with different surface areas) to hydrogen peroxide. A reaction will take place because fizzing will occur. My aim is to investigate the amount of fizzing to the surface area of the potato. Potato contains catalase, which is an enzyme, found in all aerobic tissues. Its job is to catalyse the breakdown of hydrogen peroxide into water and molecular oxygen. It's important hydrogen peroxide is removed from cells because it becomes poisonous. Enzymes are biological catalysts so they will speed up a reaction. They work as follows: I predict that when the surface area of the potato piece is increased by a constant, the rate of reaction will also increase by that constant so the surface area of the enzyme will be directly proportional to the rate of...
