Question

An organic non-protein cofactor which is easily separable from apoenzyme is called

• A. Prosthetic group
• B. Coenzyme
• C. Alloenzyme
• D. All the above

Answer 1

The correct option is B Coenzyme

A cofactor is a non-protein part of the enzyme. It can be metal ions or the organic chemical. The cofactors which are organic chemicals are known as a coenzyme. These are loosely attached to the apoenzyme. The tightly bound coenzymes are the prosthetic group. For example, a heme group is a prosthetic group consisting of a protoporphyrin ring and a central iron.

So, the correct answer is option B.
