The electron transport chain that takes place in mitochondria during cellular respiration is interconnected with several other biological pathways in the cell. These pathways include glycolysis, the preparatory reactions, and the citric acid cycle, where NADH and FADH2 molecules are synthesized. In glycolysis and citric acid cycle, 2 NADH and 3 NADH molecules are synthesized, respectively. Regarding FADH2, one molecule of this compound is synthesized per each cycle of the citric acid cycle.
