AIIMS 2014 Zoology Enzyme Activity MCQ Question
Assertion Enzymes become inactive below minimum temperature. Reason The inactivity of the enzymes is due to denaturation.
Both Assertion and Reason are true and Reason is the correct explanation of Assertion
Both Assertion and Reason are true, but Reason is not the correct explanation of Assertion
Assertion is true but Reason is false
Both Assertion and Reason are false
Correct Answer
Detailed Explanation
The assertion is true because enzymes typically have a minimum temperature below which their activity significantly decreases, leading to inactivity. However, the reason is false; enzyme inactivity at low temperatures is not due to denaturation, which generally occurs at high temperatures, but rather due to reduced kinetic energy and molecular motion that slows down enzyme-substrate interactions. Therefore, the correct answer is C: Assertion is true but Reason is false.
