SAT Biology question

Hi guys,

Does cellular respiration produce 38 ATP or 36 ATP? What does College Board want you to know it as??

And if you know the answer, could you tell me where those respective ATPs come from? (Like with NADH and FADH2 and everything)

Thank you! That would be very much appreciated

It’s been a year since I took AP Bio so this is not fresh in my mind. However, I believe it’s 38 ATP. 2 in glycolysis, 2 in Krebs cycle, 34 in the electron transport chain. According to Khan Academy, “Some books state 36 ATP per glucose but this occurs in cells that convert the 2 NADHs made in glycolysis into 2 FADH2s when they enter the mitochondria where Krebs cycle and ETC occur.” (Here’s the link if you would like to see it: https://www.khanacademy.org/questions/why-does-one-of-my/kafb_7007652) I doubt they would ask you to choose between 36 ans 38 on the exam though, since there isn’t really a definite answer.
