Inhibitors which block the enzyme by forming weak bond are called___________?
Correct answer: D. Both a and b
- A. Competitive inhibitors.
- B. Non-competitive inhibitors
- C. Irreversible inhibitors.
- D. Both a and b
Explanation
Weak, non-covalent bonds usually produce reversible inhibition, and both competitive and non-competitive inhibitors can act reversibly. Therefore, both types listed in a and b fit, making d the best choice. A likely mistake is choosing c because the inhibitor blocks the enzyme, but irreversible inhibitors usually form permanent or very strong bonds.

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.
