Question

Coenzyme is :

• A. the non-protein component of an enzyme which is loosely held by the enzyme and necessary for its biological activity
• B. the protein component of an enzyme which is loosely held by the enzyme and necessary for its biological activity
• C. the non-protein or protein component of an enzyme which is loosely held by the enzyme and necessary for its biological activity
• D. none of these

Answer 1

The correct option is A the non-protein component of an enzyme which is loosely held by the enzyme and necessary for its biological activity

A coenzyme is an organic non-protein compound that binds with an enzyme to catalyze a reaction. A coenzyme cannot function alone, but can be reused several times when paired with an enzyme. Without coenzymes or cofactors, enzymes cannot catalyze reactions effectively.
