The degree of inhibition for an enzyme-catalyzed reaction at a particular inhibitor concentration is independent of the initial substrate concentration. The inhibition follows (A) competitive inhibition (B) mixed inhibition (C) un-competitive inhibition (D) non-competitive inhibition
The degree of inhibition for an enzyme-catalyzed reaction at a particular inhibitor concentration is independent of the initial substrate concentration. The inhibition follows
(A) competitive inhibition
(B) mixed inhibition
(C) un-competitive inhibition
(D) non-competitive inhibition
Answer
Answer: (C) un-competitive inhibition
Un-competitive inhibition occurs when the degree of inhibition is independent of the substrate concentration, as the inhibitor binds only to the enzyme-substrate complex. This contrasts with competitive, mixed, and non-competitive inhibitions, which depend on substrate concentration.
