[{'content': 'Function of coenzyme is to \nSelect and explain. \nA. Enhance the specificity of apoenzyme, B. Accept one of the cleavage products, C. Activate the substrate, D. Increase the active sites of apoenzyme', 'role': 'user'}, {'content': 'Answer: C \nExplanation: Enzymes may be simple proteins , or complex enzymes, containing a non -protein pa, called the prosthetic group. The prosthetic group is called the co-enzyme.It is heat stable. The protein pa is named as apoenzyme.It is heat labile.The two poions combined together are called the HOLOENZYME. First group of co-enzymes: In the first group , the change occuring in the substrate is counter balanced by the co-enzymes.Therefore,such co-enzymes may be called as co-substrates or secondary substrates. These takes pa in reactions catalyzed by oxido-reductases by donating or accepting hydrogen atoms or electrons. Second group of coenzymes : These coenzymes take pa in reactions transferring groups other than hydrogen. A paicular group or radical is transferred from the substrate to another substrate.
