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).
In one example, the end product depends on the successful completion of five reactions, each mediated by a specific enzyme. The enzymes in a series can be located adjacent to each other (in an organelle or in the membrane of an organelle), thus speeding the reaction process.any enzymes function by lowering the activation energy of reactions. By bringing the reactants closer together, chemical bonds may be weakened and reactions will proceed faster than without the catalyst. The use of enzymes can lower the activation energy of a reaction (Ea).
