Question

Assertion : A co-enzyme or metal ion that is very tightly bound to enzyme protein called prosthetic group.

Reason : A complete, catalytically active enzyme together with its bound prosthetic group is called apoenzyeme.

• A. If both assertion and reason are true and reason is correct explanation of assertion.
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false.
• D. If both assertion and reason are false.

Answer 1

The correct option is C If assertion is true but reason is false.

Prosthetic groups refer to tightly bound coenzymes or metal ions to enzyme protein.
Enzymes are proteins which helps to catalyze the biochemical reaction. The enzyme has a protein part known as apoenzyme.
A complete, catalytically active enzyme together with its bound prosthetic group is called holoenzyme.

Therefore, assertion is true but reason is false.
