In competitive inhibition, the two things that binds to enzyme active site are?
Correct answer: D. Both A and B
- A. Substrate
- B. Inhibitors
- C. Catalyst
- D. Both A and B
Explanation
The competitive inhibitor is a molecule that closely resembles the substrate and competes with the substrate for binding to the active site of the enzyme. The inhibitor does not undergo the normal catalytic reaction and, instead, blocks the active site temporarily.

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.
