Coenzyme [edit]. A coenzyme is a small, organic, non-protein molecules that carries chemical groups between enzymes. It is the cofactor for the enzyme and does not form a permanent part in the enzyme's structure. Sometimes, they are called cosubstrates and are considered substrates that are loosely bound to the enzyme. In metabolism, coenzymes play a role in group-transfer reactions, such as ATP and coenzyme A, and oxidation-reduction reactions, such as NAD+ and coenzyme Q10. Coenzymes are frequently consumed and recycled.
coenzymes are organic molecules that are required by certain enzymes to carry out catalysis. They bind to the active site of the enzyme and participate in catalysis but are not considered substrates of the reaction.coenzymes often function as intermediate carriers of electrons, specific atoms or functional groups that are transfered in the overall reaction.hey bind to the active site of the enzyme and participate in catalysis but are not considered substrates of the reaction. coenzymes often function as intermediate carriers of electrons, specific atoms or functional groups that are transfered in the overall reaction.
