Question

The tightly bound non-proteinaceous organic compound in enzyme is ______.

Options

• coenzyme

• cofactor

• prosthetic group

• apoenzyme

Answer 1

The tightly bound non-proteinaceous organic compound in enzyme is prosthetic group.

Explanation:

A cofactor is a non-protein chemical molecule or metallic ion that is required for the action of an enzyme. Cofactors are classed as either inorganic ions or complex organic compounds known as coenzymes, the latter of which is mostly derived in small amounts from vitamins and other organic vital nutrients. A prosthetic group is a coenzyme that is strongly or even covalently bound.
