Question

what are the different stages through which NAD is regenerated​

Answer 1

Answer:

When NADH or FADH2 give their high energy electrons to the electron transport chain, NAD+ and FAD are regenerated. These low energy molecules cycle back to glycolysis and/or the citric acid cycle, where they pick up more high energy electrons and allow the process to continue.
