Co-enzymes are organic compounds but their association with the apoenzyme is only transient.

(A) Metal ions are co-factor which form coordination bonds with side chains at the active site and at the same time form one or more coordination bonds with the substrate. (B) Co-enzymes are organic compounds and their association with the apoenzyme is permanent.

Co-factor whose association with the apoemzyme is only transient

Co-enzyme is

The organic compounds, which have transient association with apoenzymes are called

Co-enzyme can function in association with an apoenzyme.

Assertion : Co-enzymes serves as co-factors in a number of differen enzymes catalysed reaction. Reason : Association of co-enzyme with the apoenzyme is only transient, usually occurring during the course of catalysis.

Organic compounds that are tightly bound to apoenzyme is
