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).
Enzymes are protein molecules that speed up a chemical reaction by lowering the activation. energy. In this experiment, the action of catalase was tested on different types of tissue extracts.n enzyme called catalase breaks down hydrogen peroxide into water and oxygen. In experiment number 3, we are comparing the action of catalase in different tissues by testing this hypothesis: The breakdown of hydrogen peroxide occurs at the same rate in all cells.
