Why is there a difference in the ATP that is being produced by the NADH molecule coming from Glycolysis which could be 4-6 for 2 NADH molecules? a.The conversion of reduction of NAD+ to NADH is a highly energetic process. b.Glycolysis uses 2 ATP for the production of NADH. c.NADH molecules from Glycolysis is not energetic enough to produce the 3 ATP. d.It will be dependent on the pathway that the NADH will be undergoing.
