Answer #1

Except Succinyl-CoA synthetase NADH reduces  α-Ketoglutarate dehydrogenase, Isocitrate dehydrogenase and Malate dehydrogenase.

Hence, the correct optioin is (b) Succinyl-CoA synthetase

----------------------------------------------------------------------------------------------------------------------

The net equation of glycolysis as it occurs in aerobic cells such as brain cells is as follws:

Glucose + 2 ADP + 2 Pi  à   2 CH3CH2OH + 2 CO2   + 2 ATP

Hence, correct option is (b)
