Enzyme Inhibition Type Characteristic A. Competitive inhibition 1. Inhibitor binds to the enzyme-substrate complex B. Non-competitive inhibition 2. Inhibitor binds to the allosteric site, reducing enzyme activity C. Uncompetitive inhibition 3. Inhibitor competes with the substrate for the active site D. Allosteric inhibition 4. Inhibitor binds to a site other than the active site
Options
- AA - 3, B - 4, C - 1, D - 2
- BA - 2, B - 3, C - 4, D - 1
- CA - 1, B - 2, C - 3, D - 4
- DA - 4, B - 1, C - 2, D - 3
Correct answer
A. A - 3, B - 4, C - 1, D - 2
Step-by-step solution
Competitive inhibition (A) involves an inhibitor that competes with the substrate (III) for the active site. Non-competitive inhibition (B) occurs when an inhibitor binds to a site other than the active site (IV). Uncompetitive inhibition (C) involves an inhibitor that binds to the enzyme-substrate complex (I). Allosteric inhibition (D) involves an inhibitor that binds to the allosteric site (II), reducing enzyme activity.
