Planning: The objective of this coursework is to investigate how the surface area of the potato affects the amount of oxygen produced from the reaction: Hydrogen peroxide water + oxygen Introduction: Enzymes are found in every living organism. An enzyme is a biological catalyst which speeds up a chemical reaction in an organism. Catalase is found in the liver but it is also found in potatoes. Catalase is known to be the fastest-reacting enzyme as it has a turnover number of six million. Catalase breaks down poisonous hydrogen peroxide in the liver to make a harmless solution (oxygen + water). This is how an enzyme works: The enzyme can work over and over again; it works rapidly since it isn't destroyed after catalysing the reaction. It is thought that each enzyme molecule has a precise place on its surface, called the active site, to which the substrate molecules become attached.
