Coenzymes play crucial roles in metabolism by:
| 1. | Acting as a temporary storage of electrons and protons. |
| 2. | Serving as structural components of cell membranes. |
| 3. | Directly participating as one of the substrates in a reaction. |
| 4. | Acting as integral membrane proteins. |

Prosthetic groups differ from co-enzymes in that
| 1. | they require metal ions for their activity. |
| 2. | they (prosthetic groups) are tightly bound to apoenzymes. |
| 3. | their association with apoenzymes is transient. |
| 4. | they can serve as co-factors in a number of enzyme-catalyzed reactions. |
