Detailed explanation-1: -FAD, in its fully oxidized form, or quinone form, accepts two electrons and two protons to become FADH2 (hydroquinone form). The semiquinone (FADH·) can be formed by either reduction of FAD or oxidation of FADH2 by accepting or donating one electron and one proton, respectively.
Detailed explanation-2: -7: The Citric Acid Cycle, Step 6. Succinate is oxidized to fumarate. During this oxidation, FAD is reduced to FADH2.
Detailed explanation-3: -During respiration, reduction-oxidation processes in the Krebs cycle produce FADH2 and NADH from FAD and NAD+, as shown below: This cycle creates FADH2 and NADH by releasing modest quantities of energy in the form of adenosine triphosphate, or ATP. The Krebs cycle works in a similar way to a wheel.
