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).
Background. The enzyme Catalase. Enzymes are proteins that help a certain chemical process take place. Chemical reactions require a certain amount of energy to take place.In the presence of the enzyme, the amount of energy required for the chemical process to take place is reduced.This happens because the enzymes bond with certain substrates to produce the end products.The reduction in the energy level helps to make the process happen faster.n the presence of the enzyme, the amount of energy required for the chemical process to take place is reduced.
