Solution
The correct option is A 2pyruvicacid+2ATP+2NADH2
In glycolysis, two molecules of ATP are consumed during two phosphorylation reactions to form fructose 1, 6-biphosphate. In return, four molecules of ATP are produced by substrate-level phosphorylation (conversion of 1, 3-biphosphoglycerate to 3-phosphoglycerate and phosphoenolpyruvate to pyruvate). Two molecules of NADH2 are formed at the time of oxidation of glyceraldehyde 3-phosphate to 1, 3-biphosphoglycerate. The net reaction of glycolysis is as follows:
Glucose+2NAD++2ADP+2H3PO4→2Pyruvate+2NADH+2H++2ATP
Each NADH is equivalent to 3 ATP, so the net gain in glycolysis is 8 ATP.
So the correct answer is '2pyruvicacid+2ATP+2NADH2'.
