Detailed explanation-1: -FADH2 in the matrix deposits electrons at Complex II, turning into FAD and releasing 2 H+.
Detailed explanation-2: -The Electron Transport Chain The ten NADH that enter the electron transport originate from each of the earlier processes of respiration: two from glycolysis, two from the transformation of pyruvate into acetyl-CoA, and six from the citric acid cycle. The two FADH2 originate in the citric acid cycle.
Detailed explanation-3: -A total of four CO2, six NADHs, two FADH2, and two ATPs are made through the citric acid cycle. NADH and FADH2 are electron carriers that can produce more ATPs later in aerobic respiration.
Detailed explanation-4: -For each pair of electrons transferred by FADH2, between 1 and 2 ATP are generated. In eukaryotic cells, unlike prokaryotes, NADH generated in the cytoplasm during glycolysis must be transported across the mitochondrial membrane before it can transfer electrons to the electron transport chain and this requires energy.
