The Michaelis constant (Km) represents
Correct answer: B. Substrate concentration at half Vmax
- A. Maximum reaction velocity
- B. Substrate concentration at half Vmax
- C. Enzyme concentration
- D. Inhibitor concentration
Explanation
Km is the substrate concentration at which the reaction velocity is half of Vmax. It indicates enzyme-substrate affinity.

About Enzyme Inhibitors
Enzyme inhibitors reduce reaction rate by interfering with enzyme-substrate interaction or catalytic activity. Coverage includes reversible competitive, non-competitive and uncompetitive inhibition, the effects of inhibitor concentration on reaction rate, and why competitive inhibition can be reduced by increasing substrate concentration.
