AIIMS 2018 Zoology Enzyme Inhibition Assertion Reason Question
Assertion: All enzymes can be inhibited Reason: Enzyme activity can be inhibited by temperature.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not correct explanation of A
A is true but R is false
A and R are false
Correct Answer
Detailed Explanation
Option B is correct because while it is true that all enzymes can be inhibited, the assertion that enzyme activity can be inhibited by temperature is misleading. Temperature can affect enzyme activity by denaturing proteins or altering their kinetic energy, but it is not a direct inhibition mechanism like competitive or non-competitive inhibition. Option A alone is true, but the reason provided does not accurately explain the assertion, making option B the best choice. Options A and R being true but R not explaining A excludes option A as a standalone explanation, while options C and D are incorrect as they misrepresent the truth of the statements.
