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).
They are similar to other chemical catalysts in many ways: 1  Enzymes and chemical catalysts both affect the rate but not the equilibrium constant of a chemical reaction. 2  Enzymes and chemical catalysts increase the rate of a chemical reaction in both directions, forward and reverse. This principle of catalysis follows from the fact that catalysts can't change the equilibrium of a reaction.
