Explanation:

The ETC activity occur in the intermembrane space. For every ATP molecule, three hydrogen ion are released during a Kerb cycle. Out of three hydrogen ion, one join with 3NAD + to produce NADH and remaining two hydrogen ion joins with FAD to form FADH2. Glucose is fully oxidized through two kerb cycle in which 6 NADH and 2 FADH2 molecules are produces. One molecule of NADH is equivalent to 3 molecules of ATP and one molecule of FADH2 is equal to 2 molecules of ATP.

Hence, in totality 32 molecules of ATP are produced in ETC
