Question

Quizplus · Accepted Answer

An organic molecule that makes an enzyme functional is called a coenzyme. Coenzymes are non-protein compounds that bind to enzymes and help them perform their function. Examples of coenzymes include vitamins such as riboflavin and niacin. Buffers are substances that can help maintain a stable pH in a solution, but they do not make enzymes functional. Catalysts are substances that increase the rate of a chemical reaction but do not necessarily make enzymes functional. Coactivators are similar to coenzymes but specifically refer to molecules that bind to a specific region of an enzyme to enhance its activity.
