(c) : Glycolysis or EMP pathway is the breakdown of glucose to two molecules of pyruvic acid through a series of enzyme mediated reaction releasing energy. Pyruvic acid is a 3 -carbon compound. In glycolysis net gain of 2ATP and 2 NADH ‌2 molecules occurs. It can be represented in equation form as - C6H12O6+2‌ADP+2‌Pi+2‌NAD‌‌→‌‌2CH3‌COCOOH+2‌ATP+2NADH2
