The effect of competitive inhibitor on enzyme activity is such that it affects which of the following?
Correct answer: C. Decreases enzyme activity
- A. Increases enzyme activity
- B. Doesn't change enzyme activity
- C. Decreases enzyme activity
- D. None of these options is correct
Explanation
A competitive inhibitor affects enzyme activity by directly competing with the substrate for binding to the active site of the enzyme. The binding of the competitive inhibitor to the active site results in a decrease in the rate of product formation, as the substrate is hindered from interacting with the enzyme.

About Enzymes
Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
