Question: Function of coenzyme is to
Options:
A. Enhance the specificity of apoenzyme
B. Accept one of the cleavage products
C. Activate the substrate
D. Increase the active sites of apoenzyme
Which is the correct option?<|im_end|>
<|im_start|>assistant
The correct option is C: Activate the substrate. Explanation: 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.
