Question

Glyceraldehyde-3-phosphate + NAD+ +  Pi   →    1,3-bisphosphoglycerate + NADH  +  H+

∆G0’ =+6.3 kJ mol-1

②       NAD+ +  H+  + 2e-  →   NADH          ∆G0’ = +61.7 kJ mol-1

③         Glyceraldehyde-3-phosphate + Pi   →   1,3-bisphosphoglycerate +  H+ + 2 e-       

∆G0’ = ??? kJ mol-1

How are equations ② and ③ related to equation ①?

b) Calculate the ∆G0’ for the formation of 1,3-bisphosphoglycerate from glyceraldehyde-3-phosphate and inorganic phosphate (reaction ③ above)

c) Why is reaction ③ coupled with the reaction ② when reaction ② is so unfavorable, i.e., what is the chemical role of the NAD+?
