by G3p I mean Glyceraldehyde 3-phosphate and i thought it would be that because i assumed NADH was that same as NAD2H and G3P is the only metabolite of gluconeogenesis that uses it. But i wasn't sure about the answer because the question continues to ask why the deuterium label taken up by G3P may not show up in the final product of glucose which i don't really understand.

For deuterated NAD2H is the first metabolite of gluconeogenesis to incorporate the label G3P? 1. Asked to calculate the moles of protons pumped out of the mitochondrial matrix per mol of FMN molecule as electrons are passed on to coenzyme-Q. First I used this equation: ∆G = -2.303RT(pHout – pHin) + ZF∆yto calculate kj/ mol of protons and that's where I got stuck and don't know what to do next and ∆Gº’= -73.3 kJ/mol ∆pH= 1.3 ∆y= 0.18V and T= 37C. Please help! 2. Asked to calculate how many molecules of FMNH2 need to get oxidized to make 450 g ATP. DG for hydrolysis of ATP is -50.2 kJ/mol and the efficiency of ATP synthase is 40.2% and MM of ATP= 503.15g/mol. For this question i began by calculating the moles of ATP and than I multiplied the DG for hydrolysis of ATP with the efficiency and thats as far as I got. I'm not sure what to do next.
