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)
34 ATP molecules are produced by the end of the electron transport chain.
Approximately 30-32 molecules of ATP are produced by oxidative phosphorylation for each glucose molecule that enters glycolysis.
In a complete Krebs Cycle, 24 ATP are produced. Every glucose molecule produces 2 ATP, and there are 12 glucose molecules.
Acetyl coenzyme A is produced twice from one molecule of glucose in the process of glycolysis and the citric acid cycle. Each glucose molecule is broken down into two molecules of pyruvate during glycolysis, and each pyruvate molecule is converted to one molecule of acetyl CoA before entering the citric acid cycle.
Six oxygen molecules are released when one glucose molecule is formed.

2 ATP are produced in anaerobic respiration(fermentation)
Six CO2 molecules will be produced for every glucose molecule completely oxidized. Glucose contains six Carbon atoms, hence the six CO2 molecules.
If 2 NADH molecules were produced in glycolysis, it means that 1 glucose molecule was broken down. Each glucose molecule yields 2 NADH molecules during glycolysis.
