Which of the following statements about coenzymes is FALSE?

Question

Quizplus · Accepted Answer

The statement about coenzymes that is false is that coenzymes reduce the speed of enzymatic reactions. Coenzymes actually increase the speed of enzymatic reactions.
Key Takeaway: A coenzyme is any substance that binds to an enzyme and is required for its maximal activity. Coenzymes work by lowering the activation energy of an enzyme. Coenzymes can either bind to the active site along with the substrate or to another site on the enzyme. Coenzymes can either be organic (ex. heme, flavin) or inorganic (ex. Mg2+, Mn2+) non-protein entities. Some enzymes must have more than one coenzyme bound to become active.
