BIO NMDCAT ENZYMES

nmdcat.online July 11, 2026

In living organisms, the most fundamental role of an enzyme is to

A. Provide energy for a nonspontaneous reaction

B. Shift the equilibrium towards product formation

C. Increase the reaction rate by lowering activation energy

✓

D. Alter the standard free energy change of a reaction

📝 Explanation

Enzymes are biological catalysts that accelerate reactions by decreasing the activation energy. They do not provide energy, alter the equilibrium constant, or change the free energy change (ΔG) of the overall reaction.
