Contrast and compare cofactors versus coenzymes.

Description : Contrast and compare cofactors versus coenzymes.

Last Answer : Cofactors are “adjunct” enzymes that require non­protein helpers for catalytic activity. An organic molecule that is a cofactor would be a coenzyme. Cofactors are often required in catalysis. The cofactors of some enzymes, however, are inorganic.
