Question

Loss of activity which may be restored by the removal of inhibitor is referred to as ___________

(a) reversible inhibition

(b) irreversible inhibition

(c) competitive inhibition

(d) mixed inhibition

I had been asked this question by my school teacher while I was bunking the class.

This intriguing question comes from Fundamentals in section Enzyme Kinetics Fundamentals of Enzyme Technology

Answer 1

Correct answer is (a) reversible inhibition

For explanation I would say: Reversible inhibition is one where in loss of activity of activity may be revived by removal of inhibitor. As compared to, irreversible inhibition where the loss of activity cannot be restored. Mixed inhibition is one where in both EI and ESI complexes are formed with no product formation. Competitive inhibition occurs when both substrate and the inhibitor compete for binding to active site.
