I was wondering if someone could explain to me where all the ATP comes from from the complete oxidation of glucose. We said in class complete oxidation yields ~30ATP. I pretty much have where all the ATP comes from so far except my math is a little off. We said in class 2.5 ATP come from NADH when e- 's are transferred to O2. Thus in the TCA cycle I count 4 places where NADH is given off 4x2.5=10ATP multiply that by 2 since there are two copies of pyruvate after glycolysis for 1 glucose molecule so there are 20ATP. In another step in the TCA cycle 1 GTP is given off so 2x1GTP=2 NTPs. That gives 22 ATPs In another step in TCA cycle there is 1FADH given off, which we said in class yields 1.5 ATP, so 2x1.5=3 ATP so we have 25 ATP. 4 NTPs from glycolysis so 29 ATPs. Finally there is 1 cytosolic NADH that is given off during glycolysis. In class we said cytosolic NADH yields 1.5 ATP. So 2x1NADH=2NADHx1.5=3ATP For a grandtotal of 32ATP. In the handout notes my prof. gave us he said there should be 30 ATP, where did I go wrong?
