Multiple choice At the end of glycolysis, the hexose sugar gets converted into pyruvic acid acetyl-CoA NAD D-amino-acid dehydrogenase NADH Reveal answer Fill a bubble to check yourself A Correct answer Explanation 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 NADH2 molecules occurs.
