1st answer - one glucose molecule oxidised 38 ATP molecules produced during cell

Question

1st answer - one glucose molecule oxidised 38 ATP molecules produced during cellular respiration

2 from glycolysis

2 from the Krebs cycle, and about

34 from the electron transport system)

2nd answer - Total 38 ATPs are produced from cellular respiration in the presence of oxygen.

Glycolysis: 8 ATP

Conversion pyruvate to acetyl coA: 6ATP

Kreb's cycle: 24ATP

MY QUESTION: I am confused. 2 answers on chegg study on "how many APT is produced from 1 molecule of glucose?" are different. Please explain.

Explanation / Answer

In my opinion and if you study aerobic respiration -

One molecule of glucose yields 38 ATP molecules. In which 8 produced during glycolysis, 6 from the link reaction and 24 from the Krebs cycle.

Accordingly, the net gain is 36 ATP, as 2 of the ATP molecules produced from glycolysis are used up in the re-oxidation of the hydrogen carrier molecule NAD.

I think you understand the above. In case of any query please write to me.
