The Electron Transport Chain(System) consists of a series of redox carriers in the inner membrane of the mitochondria in eukaryotes and the plasma membrane in aerobic prokaryotes that receive electrons from NADH and FADH,which are produced in Glycolysis Fat oxidation Citric Acid Cycle at the end of the pathway,the electrons,along with protons are donated to oxygen to form H,OThe Electron Transport Chain (System) - consists of a series of redox carriers in the inner membrane of the mitochondria in eukaryotes and the plasma membrane in aerobic prokaryotes that receive electrons from NADH and FADH2 which are produced in Glycolysis Fat oxidation Citric Acid Cycle - at the end of the pathway, the electrons, along with protons are donated to oxygen to form H2O
