- AThe inhibitor binds to the active site of the enzyme and decreases $V_{\max}$.
- BThe inhibitor binds away from the active site and increases the Michaelis-Menten constant.
- CThe inhibitor decreases $V_{\max}$, but the Michaelis-Menten constant does not change.
- DThe inhibitor does not change $V_{\max}$ but increases the Michaelis-Menten constant.
