FADH2 allows for the formation of 2 molecules of ATP during the Kreb's cycle.

One acetyl group produces 1 molecule of FADH2 in the citric acid cycle.
Two water molecules are formed by a total of 6 atoms: 2 from each oxygen atom and 1 from each hydrogen atom.
Two ATP molecules are produced from one FADH2 going through the electron transport chain. For every NADH, three ATP molecules are produced.

For each mole of pyruvate, the Krebs cycle produces 3 molecules of NADH, 1 molecule of FADH2, and 1 molecule of ATP. Therefore, from 2 moles of pyruvate, the Krebs cycle produces 6 molecules of NADH, 2 molecules of FADH2, and 2 molecules of ATP. These NADH and FADH2 molecules go on to generate more ATP through oxidative phosphorylation in the electron transport chain.

One acetyl group produces 1 molecule of FADH2 in the citric acid cycle.
From glycolysis two pyruvates are produced per molecule of glucose. Pyruvate is converted to acetyl CoA which enters the Kreb's cycle. Therefore, one molecule of glucose eventually creates 2 turns of the Krebs cycle. The cycle produces 1 ATP, 3 NADH, and 1 FADH2 per turn. So for each molecules of glucose you will have 2 FADH2.
20 ATP from 8 NADH 12 ATP from 12 FADH2 9 acetyl co-A --> 9 GTP, 67,5 ATP from 27 NADH, 13,5 ATP from 9 FADH2 minus 2 ATP to start beta-oxidation = 120 ATP

Approximately 34 molecules of ATP are produced during oxidative phosphorylation in the electron transport chain. Each NADH molecule yields about 3 ATP, while each FADH2 molecule yields about 2 ATP.
