Enzymes speed up the rate of chemical reactions by lowering the energy of activation (the amount of energy needed to begin a reaction).nzymes speed up the rate of chemical reactions by lowering the energy of activation (the amount of energy needed to begin a reaction).
An enzyme is described as a biological catalyst that speeds up the rate of a chemical reaction. In order for an enzyme to perform its given job, it needs what is known as a substrate to bind to the active site of the enzyme so that the enzyme can speed up the reaction of the substrate. In this given experiment, it was to be tested what impact the concentration level of substrate will have on the reaction rate. The enzyme catalase, found in potato juice, was used for the catalyst along with a substrate known as hydrogen peroxide (H2O2). The job of catalase in this experiment was to accelerate the breakdown of hydrogen peroxide into water and oxygen gas.
