Question

How are prosthetic groups distinguished from other cofactors?

Answer 1

Cofactors:

1. A cofactor is a substance essential for enzyme activity.
2. Cofactors can be either organic or inorganic molecules.
3. They are not chemically bound to the enzymes but participate in the chemical reactions.

Prosthetic groups:

1. A prosthetic group is a non-protein compound tightly bound to the enzyme to aid its function.
2. Vitamins and minerals are examples of cofactors.
