• Enzyme’s activity can be specific which means the activity is limited to a certain substrate and a certain type of reaction and it is referred to as specificity of the enzyme.

Cofactor: It is a non-protein part of an enzyme which is essential to the enzyme’s catalytic activity and it can be a cofactor or a coenzyme.

Coenzyme: It is an organic molecule that acts as an enzyme cofactor.
