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).
An enzyme lowers the activation energy of a chemical reaction. c. Most enzymes are proteins. d. An enzyme is consumed during the reaction it catalyzes. e. An enzyme is very specific in terms of which substrate it binds to.nzymes can change the equilibrium point of reactions, but they cannot speed up reactions because they cannot change the net energy output. b. Enzymes can greatly speed up reactions, but they cannot change the net energy output because they cannot change the activation energy.
