5. Among the following statements, the effect of irreversible inhibitors is best described as

A. Permanent loss of enzyme activity
✓
B. Temporary occupation of the active site
C. Increased substrate affinity
D. Formation of additional enzyme molecules

📝 Explanation

Irreversible inhibitors form stable covalent or very strong bonds with enzymes, permanently inactivating them. Other options are inconsistent with irreversible inhibition. Concept tested: Irreversible inhibition.
