How are prosthetic groups different from co-factors?

Explanation

To understand the difference between prosthetic groups and cofactors, let's break down the concepts step by step:

### Step 1: Definition of Prosthetic Groups
- Prosthetic groups are organic compounds that are tightly bound to an enzyme, specifically to the apoenzyme, which is the enzyme without its cofactor.
- The binding of the prosthetic group to the apoenzyme can occur through covalent or non-covalent interactions.

### Step 2: Example of Prosthetic Groups
- A common example of a prosthetic group is heme, which is found in enzymes like peroxidase and catalase.
