Aim My aim for this investigation is to measure the amount of oxygen given off when we react catalase (enzyme) with hydrogen peroxide (substrate), this means that I aim to investigate the effect of hydrogen on the activity of catalase. Background Information Enzymes such as Catalase are protein molecules that are found in living cells. They are used to speed up specific reaction in the cell. The enzymes are all very specific as each enzyme performs one particular reaction. Catalase is an enzyme found in many foods such as potato and liver. It's used for removing Hydrogen Peroxide from cells. Hydrogen Peroxide is the poisonous product of metabolism. Catalase speeds up the decomposition of Hydrogen Peroxide into oxygen and water. Variables I will make sure I keep the following variables the same. Size of potato: The Size of a potato cube would effect the investigation because the size of the cube would effect the number of cells...
