← ScienceWhich consequence results when an inhibitor slows enzyme kinetics?
A)Substrate binding site steric hindrance
B)Increased reaction equilibrium constant
C)Elevated product synthesis reaction rate
D)Decreased enzyme catalytic turnover frequency✓
💡 Explanation
Decreased enzyme catalytic activity occurs because competitive/noncompetitive inhibition impacts transition state stabilization during catalysis, decreasing the enzyme's turnover frequency rather than the equilibrium constant. Therefore, the reaction rate slows down rather than increasing it.
