What is the effect of varying the substrate concentration on the rate at which oxygen is give off when Hydrogen Peroxide is added to potato chips? Background Information Hydrogen Peroxide is found as a bi product of reactions in every cell of the body. In each cell Catalase is also found. It helps to remove the Hydrogen Peroxide from the cells, as Hydrogen Peroxide is toxic in large amounts. Catalase speeds up the reactions of the decomposition of Hydrogen Peroxide: Catalase Hydrogen Peroxide---------------------->Water + Oxygen Catalase 2H2O2------------------->2H2O+O2 It is able to speed up the decomposition of Hydrogen Peroxide because the shape of it's active site matches the shape of the Hydrogen Peroxide molecule. It reacts because when it fits the enzyme twists it apart. This type of reaction where a molecule is broken down into smaller pieces is called a catabolic reaction. For all reactions to occur activation energy is needed....
