Cofactors
The first type of enzyme partner is a group called cofactors, or molecules that increase the rate of reaction or are required for enzyme function. Cofactors are not proteins but rather help proteins, such as enzymes, although they can also help non-enzyme proteins as well. Examples of cofactors include metal ions like iron and zinc.
Coenzymes
A specific type of cofactor, coenzymes, are organic molecules that bind to enzymes and help them function. The key here is that they're organic. 'Organic' does not mean you'll find them in a special aisle in the grocery store. Rather, organic molecules are simply molecules that contain carbon. Don't let the name 'coenzymes' fool you, either; coenzymes are not really enzymes. As the prefix 'co-' suggests, they work with enzymes. Many coenzymes are derived from vitamins.

Enzymes are composed of one or several polypeptide chains. However there are no. of cases In which non-protein constituent is present in enzymes which is called COFACTORS.
Cofactors are of three types:
1) Prosthetic Group
2)Co-enzymes
3) Metal ion
COENZYMES--
They are organic compounds.
The essential components of many coenzymes are vitamins. Example-- Coenzyme NAD (nicotinamide adenine dinucleotide) and NADP contains vitamin niacin.
