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. |

In peroxidase and catalase:
| 1. | haem is the prosthetic group and it is a part of the active site of the enzyme. |
| 2. | FAD is the prosthetic group and it is a part of the active site of the enzyme. |
| 3. | haem is the prosthetic group and is not a part of the active site of the enzyme. |
| 4. | NADP is the prosthetic group and it is a part of the active site of the enzyme. |
