You are observing an enzyme driven reaction. You add chemical X, which inhibits the reaction. If you add more substrate, the reaction rate approaches the V_max of the uninhibited reaction. Furthermore, the structure of X is similar to the natural substrate. What kind of inhibitor is X?

Question

Quizplus · Accepted Answer

Chemical X is inhibiting the enzyme in a way that can be overcome by adding more substrate, indicating that it is a competitive inhibitor. Additionally, the fact that X has a similar structure to the natural substrate supports this conclusion.
