Answer :
Answer:
During Glycolysis 2 molecules of NADH are formed.
Explanation:
When the glycolytic intermediate glyceraldehyde-3-phosphate is converted to 1,3-bisphosphoglycerate by the catalytic activity of glyceraldehyde -3-phosphate dehydrogenase at that time 2 molecules of NAD+ undergo reduction to form 2 molecules of NADH.
The so formed NADH enters into the electron transport chain to generate ATP.
