Question

Quizplus · Accepted Answer

Proteins serve various functions in the body, including muscle contraction, transport of substances like blood lipids, maintaining blood viscosity and osmolarity, and catalyzing enzymatic reactions. However, proteins themselves do not serve as cofactors for enzymes. Cofactors are non-protein chemical compounds or metallic ions that assist enzymes in their catalytic activity.
