Coenzymes are small organic non-protein molecules that carry chemical groups between enzymes. Many coenzymes are phosphorylated water-soluble vitamins. However, nonvitamins may also be coenzymes, such as ATP, the biochemical carrier of phosphate groups.
Coenzymes are used up in the reactions in which they assist, (for example: NADH coenzyme is converted to NAD+ by oxidoreductses). Coenzymes are however regenerated and their concentration maintained at a steady level in the cell.
A special subset of coenzymes is prosthetic groups. These have more in common with cofactors since they are tightly bound to enzymes and are not released as part of the reaction. Prosthetic groups include molybdopterin, lipoamide and biotin.

acetyl coA is an enzyme that would have to be common because it is essential in the krebs cycle during cellular respiration
