In aerobic respiration, one molecule of glucose yields 38 ATP molecules, eight produced during glycolysis, six from the link reaction and 24 from the Krebs cycle.
The net gain is 36 ATP, as two of the ATP molecules produced from glycolysis are used up in the re-oxidation of the hydrogen carrier molecule NAD.
Therefore;
There are 38 ATP molecules produced
but net gain is 36 ATP
2 ATP are produced in anaerobic respiration(fermentation)
The total ATP produced from one glucose is --------* (36/38) ATP
38 ATP molecules are produced from the break down of a gluecose molecule
Approximately 30-32 molecules of ATP are produced by oxidative phosphorylation for each glucose molecule that enters glycolysis.
34 ATP molecules are produced by the end of the electron transport chain.

In anaerobic respiration, 2 ATP molecules are produced per glucose molecule through glycolysis.
Two, net.

In anaerobic respiration one glucose molecule produces a net gain of two ATP molecules (four ATP molecules are produced during glycolysis but two are required by enzymes used during the process). In aerobic respiration a molecule of glucose is much more profitable in that a net worth of 34 ATP molecules are generated (32 gross with two being required in the process).
In a complete Krebs Cycle, 24 ATP are produced. Every glucose molecule produces 2 ATP, and there are 12 glucose molecules.
