Which statement about enzymes is true? an enzyme functions to increase the rate of a chemical reaction. enzymes are proteins that function as catalysts in nonliving things. each enzyme can catalyze many different biochemical reactions.. enzymes and substrates fit together like a lock and key.

Each enzyme can catalyze many different biochemical reactions..

Explanation:

An enzyme is a protein that catalyzes the biochemical reactions of metabolism. Enzymes act on molecules known as substrates and allow the development of various cellular processes. It is important to note that enzymes do not modify the energy balance or chemical equilibrium of those reactions in which they intervene: their function is limited to helping speed up the process. This means that the reaction under the control of an enzyme reaches its equilibrium much faster than a non-catalyzed reaction. Enzymes are estimated to catalyze about 4,000 different biochemical reactions.
