multiple choice question which of the following is a cofactor but not a coenzyme? glucose zinc many proteins…

Brief Explanations:

Cofactors are non - protein chemical compounds or metallic ions that assist enzymes in their catalytic activity. Coenzymes are organic non - protein molecules that bind to the active site of an enzyme and participate in catalyzing the reaction. Zinc is a metallic ion and is a cofactor but not a coenzyme. Glucose is a sugar and not a cofactor or coenzyme. Proteins are not typically cofactors in the sense described here. Fats are also not cofactors or coenzymes relevant to this context.

Answer:

Zinc
