AIIMS 2018 Zoology Types of Inhibition Assertion Reason Question

Option A is correct because the assertion states that a non-competitive inhibitor binds to the enzyme at a site other than the active site, which is true, while the reason incorrectly describes the role of a competitive inhibitor, which does bind to the active site but does not change its structure. Option B is incorrect because, although both statements are true, the reason does not correctly explain the assertion. Option C is incorrect since the assertion is true, and the reason is false. Option D is incorrect because the assertion is true, making this option invalid. Understanding the distinction between competitive and non-competitive inhibitors is crucial for grasping enzyme kinetics and regulation.
