Dear student,
Please find below the solution to the asked query

The respiratory balance sheet of aerobic respiration of one molecule of glucose can be explained as under:
 

Step	No. of ATP produced
Glycolysis	2NADH2= 2 x 3 = 6ATP 2ATP (Substrate level) Total = 8ATP
Linking reaction Pyruvate to Acetyl coenzyme A	2NADH2= 2 x 3=6 ATP
Kreb's cycle	6NADH 2​= 6 x 3=18ATP 2FADH= 2 x 2=4ATP ​2ATP (Substrate level) Total= 24ATP
Total of all steps	8+6+24= 38ATP

ETS helps to release and utilise the energy stored in NADH₂ and FADH₂ synthesised above and converts them to ATPs. During ETS, the number of ATP produced depends on the nature of electron donor. In this reaction, the NADH gives 3 molecules of ATP while the FADH₂ give two molecules of ATP.

Hence, the net gain of 38ATP molecules occurs during aerobic respiration of one molecule of glucose.​
