Coenzymes Coenzymes are small molecules which often work together with enzymes to enhance the reaction rate. Coenzymes tend to be low mw organic molecules which serve as carriers for several types of chemical groups. NAD- nicotinamide adenine dinucleotide Functions as a carrier of electrons in oxidation- reduction reactions. NAD may accept a [H+] and 2 electrons to become NADH from 1 substrate and then donate the electrons to a second substrate. Other examples of coenzymes which are electron carriers: NADP, FAD, etc.

Unformatted text preview: Other coenzymes may be involved with the transfer of carboxyl and acyl groups. Some coenzymes may function with a variety of different enzymes. Many coenzymes are closely related to vitamins. The vitamin often contributes all or part of the structure of certain coenzymes. Although not required for prokaryotic cells, vitamins are required in the diets of humans and other higher animals....
