A substance which binds at the active site of the enzyme but does not result in the formation of the products is called________________?
Correct answer: C. Competitive inhibitor
- A. Irreversible inhibitor
- B. Reversible inhibitor
- C. Competitive inhibitor
- D. Non-competitive inhibitor
Explanation
A competitive inhibitor resembles the substrate and binds to the enzyme's active site, preventing the substrate from forming products. A common mistake is choosing a reversible inhibitor, but that describes the strength of binding rather than the specific location of binding.

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.
