Answer» Correct option: (2) (A) is true but (B) is false. Explanation: Coenzyme or metal ion that is tightly bound to enzyme protein is called prosthetic group. A complete catalytic active enzyme with its bound prosthetic group is called holoenzyme. Actually , Coenzymes and metal Ions that are bound very tightly to the enzyme protien are called prosthetic groups ! This is absolute correct statement . This is because coenzymes are of two types - cosubstrates which are loosely bound and prosthetic grup which are tightly bound . A complete catalytic active enzyme with its bound prosthetic group is called holoenzyme . So A is true and B is false |
