In aerobic respiration, 36 or 38 molecules of ATP per molecule of glucose, depending on how many are gained through the electron transfer system. In anaerobic respiration 2 molecules of ATP per molecule of glucose, though higher yields can occur in higher temperatures (as much as 9 ATP molecules per molecule of glucose)
In aerobic respiration, 1 molecule of glucose yields 38 ATP molecules, 8 are produced during glycolysis, 6 from the link reaction and 24 from the Krebs cycle.
The net gain is 36 ATP, because 2 of the ATP molecules produced from glycolysis are used up in the re-oxidation of the coenzyme NAD+.
ΔG from using one mol of ATP
is ~ -30.5 kJ/mol
ΔG for the oxidation of glucose
C6H12O6 (aq) + 6 O2 (g) → 6 CO2 (g) + 6 H2O (l) is ~ -2880 kJ/mol
If you divide the ΔG for the oxidation of glucose by the ΔG for the use of one mole of ATP you get the approximate for the number of ATP produced by one mole of glucose.
1 molecule of glucose in:
-Aerobic Respiration (Eukaryotes)- 36 ATP
-Aerobic Respiration (Prokaryotes)- 38 ATP
-Anaerobic Respiration- fewer than 38 but more than 2 ATP
-Fermentation- 2 ATP
32 molecules of ATP ( net gain ).
Explanation:2 molecules of ATP - in Glycolysis ( net gain ).
2 molecules of ATP - in Krebs Cycle.
28 molecules of ATP - in Electron Transport Chain.
- 1 NADH produces x2.5 ATP ( there are 10 NADH produced )
- 1 FADH2 produces x1.5 ATP ( there are 2 FADH2 produced )
Total: 2 + 2 + 2.5x10 + 1.5x2-> 4 + 28 = 32 molecules of ATP36 atp
38 ATP

In a complete Krebs Cycle, 24 ATP are produced. Every glucose molecule produces 2 ATP, and there are 12 glucose molecules.
The total amount of ATP produced during fermentation is 2 for every glucose molecule.
2 ATP are produced in anaerobic respiration(fermentation)
