Prosthetic groups differ from co-enzymes, in which:
| 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. |
