Biomolecules Question 1
Question: Given below are two statements:
Statement I: Low temperature preserves the enzyme in a temporarily inactive state whereas high temperature destroys enzymatic activity because proteins are denatured by heat.
Statement II: When the inhibitor closely resembles the substrate in its molecular structure and inhibits the activity of the enzyme, it is known as competitive inhibitor.
In the light of the above statements,
choose the correct answer from the options given below:
(1) Statement I is false but Statement II is true.
(2) Both Statement I and Statement II are true.
(3) Both Statement I and Statement II are false.
(4) Statement I is true but Statement II is false.
Show Answer
Answer: (2) Both Statement I and Statement II are true.
Explanation-
- Statement I is true because low temperatures can preserve enzymes in an inactive state without denaturing them, while high temperatures can denature proteins, thereby destroying enzymatic activity.
- Statement II is true because a competitive inhibitor is a molecule that closely resembles the substrate and competes for binding to the active site of the enzyme, thereby inhibiting its activity.
