Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
An organic non-protein compound that binds with an enzyme to catalyze a reaction
A
Cofactors
B
Coenzymes
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -A cofactor is a non-protein chemical compound that is bound i.e, cofactors are non-protein organic molecules that are mostly derivatives of vitamins soluble in water by phosphorylation; they bind apoenzyme to proteins to produce an active holoenzyme.

Detailed explanation-3: -The non-protein part of an enzyme is a Cofactor. It is a non-protein chemical compound or metallic ion that is required for an enzyme’s activity. Apoenzyme and cofactor together form a holoenzyme.
