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.

Best answer

Answer: 2. Both Statement I and Statement II are true.

Key idea: Both statements are standard facts about enzymes.

  • Statement I is true: low temperature only makes the enzyme temporarily inactive, while high temperature denatures the protein and destroys activity.
  • Statement II is true: a competitive inhibitor looks like the substrate and competes for the active site.

Option 2.
