Actual amount of ATP produced by oxidative phosphorylation?

So I heard NADH2 actually only makes 2.5 and 1.5 ATP for FADH2.
I do know that NADH2 in glycolysis makes 1 ATP less than expected due to its transportation.

32 atp in oxidative phosphorylation.

As far as i remember correctly, they use 2 atp to transfer into the matrix of mitochondria.

that's right doc, at least that was what was taught in biochem, but for all intents and purposes for the DAT round it to 3 per NADH and 2 per FADH2. As for net we're looking at 36ATP for ETC and 38 gross

Blah! There are so many different sources on this. Mine says 34 ETC, 36 overall... But I had an achiever question today that had 38 as the answer... They didn't -2 for the transport into mitochondria..,

Glycolysis: 2NADH produced x 2ATP/NADH (have to cross membrane) = 4

Pyruvate Decarboxylation: 2NADH produced x 3ATP/NADH = 6

TCA: 6NADH x 3 =18
2FADH2 x 2 = 4

4 + 6 + 18 + 4 = 32 for oxidative

If you add in the 2 ATP from Glycolysis and 2 ATP/GTP produced in Krebs, you have 36 for total respiration in Eukaryotes.

yeah... It depends where u subtract the ATP.... Kaplan brings all the nadh(10) and fadh(2) to the Etc.... And that makes 34, the other ATP that are subtracted out....are in diff spots... I duno if that makes sense but I find that sometimes questions are not clear on what they mean

Yes it should be 36. Those value that you presented are suppoviely more accurate from the Princeton book, however, the widely accepted concept is the rounded up values.
