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 allow many chemical reactions to occur within the homeostasis constraints of a living system. Enzymes function as organic catalysts. A catalyst is a chemical involved in, but not changed by, a chemical reaction. Many 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. catalyst is a chemical involved in, but not changed by, a chemical reaction.
