Even though they are organic molecules, coenzymes are not proteins, as enzymes are, and they are not catalytically active themselves, which perhaps makes cosubstrate or cofactor a less confusing name for them. In many reactions catalyzed by enzymes, electrons or groups of atoms are transferred from one compound to another, and this usually involves a coenzyme, which temporarily accepts the group being transferred.
