J Neenan, Page 1 of 9 Investigation To Show The Affect of pH on Potato Catalase When Breaking Down Hydrogen Peroxide. Aim. I intend to investigate and carry out a fair experiment that will show how pH effects the potato enzyme Catalase when it is breaking down Hydrogen Peroxide. Background Information. Enzymes are biological catalysts that speed up reactions within living organisms by up to 1020. They consist of large protein molecules and regulate the reaction without being changed themselves. They are very selective of the following: * Most enzymes will only be effective on certain compounds or compound groups. * As the temperature increases so does the efficiency of the enzyme, until about 50 degrees Centigrade, when it becomes denatured. * All enzymes have an optimum pH this is usually the same pH as the environment in which it works. Catalase is the most powerful enzyme known, and in animals is mainly found in the liver,...
