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).
Rating Newest Oldest. Best Answer: Enzymes are proteins that accelerate, or catalyze, chemical reactions. Like all catalysts, enzymes work by providing an alternative path of lower activation energy for a reaction and dramatically accelerating its rate.Some enzymes can make their conversion of substrate to product occur many millions of times faster.ike all catalysts, enzymes work by providing an alternative path of lower activation energy for a reaction and dramatically accelerating its rate.
