Biology coursework SC1 Rate of reaction between the enzyme Catalase And Hydrogen Peroxide Background Enzymes are biological catalysts that speed up reactions. Catalase is an enzyme, and one of the fastest ones that are known to man. It breaks down Hydrogen Peroxide at 30 centigrade at a rate of 100,000 molecules per second. This is an extremely fast rate of reaction. Catalase is found in organisms such as potatoes. Therefore, as a source of Catalase, I will use a potato in order to obtain it. Enzymes are catalysts, and so, once they are used up, they can be re-used over and over again (in theory). Hydrogen Peroxide Catalase enzyme oxygen + water [Substrate] [Enzyme] [products] 2H2O2 Catalase enzyme O2 + 2H2O PLAN I will be testing the surface area of the potato slices. The more slices that I cut out, the greater the surface area will be. I will obtain the potato...
