which statement about enzymes is true? an enzyme functions to decrease 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.
Answer
Brief Explanations:
Enzymes are biological catalysts. They have specific active - sites where substrates bind in a lock - and - key model. Enzymes increase reaction rates, are proteins that function in living organisms, and are highly specific to certain reactions.
Answer:
Enzymes and substrates fit together like a lock and key.
