The structure of an enzyme is altered by____________?
Correct answer: A. Irreversible inhibitor
- A. Irreversible inhibitor
- B. Reversible inhibitor
- C. Competitive inhibitor
- D. Non-competitive inhibitor
Explanation
Irreversible inhibitors permanently alter an enzyme, often by forming strong covalent bonds with amino acids needed for its structure or active site. A common mistake is choosing non-competitive inhibitor, because it binds away from the active site, but non-competitive binding can still be reversible and need not permanently change the enzyme.
