The protons return to the matrix by flowing through ATP synthase, powering the synthesis of ATP. 1. Flavin adenine dinucleotide, or FADH2, is a redox cofactor that is created during the Krebs cycle and utilized during the last part of respiration, the electron transport chain. Glycolysis, which leads to the formation of ATP occurs in the cytoplasm gives energy for metabolism in the cells after is being broken down produces NADH. This reaction releases acetyl-CoA, FADH2 and NADH, the three of which then enter another metabolic process called citric acid cycle or Krebs cycle, in which ATP is produced to be used as energy. A deficiency of NADH will result in an energy deficit at the cellular level, which causes symptoms of fatigue. c. moved between… NADH and NADPH are coenzymes that play an important role in various bodily functions.
