← ScienceWhich outcome occurs when an inhibitor reduces enzyme turnover rate?
A)Substrate affinity appears to decrease✓
B)Reaction shifts towards hydrolysis reaction
C)Enzyme becomes structurally unstable
D)Product concentration reaches to equilibrium
💡 Explanation
Substrate affinity decreases with a reduction in enzyme turnover rate, because the inhibitor decreases the *catalytic efficiency* of enzyme. Therefore, substrate binding becomes less effective , rather than the enzyme becoming unstable or shifting equilibrium.
