This is the last complex of the chain and is involved in the transfer of two electrons from cytochrome c to molecular oxygen (O2) forming water. The Electron Transfer Function of Cytochrome c. Interaction of cytochrome c, ferrous ion, and phosphate. Energy is produced during the transfer of electrons which is utilized to pump protons across the membrane aiding to the potential gradient. n. Abbr. D H Heacock, R Q Liu, C A Yu, L Yu, B Durham, F Millett. What is the main function of the electron transport chain? c Effect of specific lysine modification on the reduction of cytochrome c by succinate-cytochrome c reductase. This stage is crucial in energy synthesis as all oxidative steps in the degradation of carbohydrates, fats, and amino acids converge at this final stage of cellular respiration, in which the energy of oxidation drives the synthesis of ATP. Binding of cytochrome c to the cytochrome bc1 complex (complex III) and its subunits cytochrome c1 and b. P. DiMaria, E. Polastro, R.J. DeLange, S. Kim, W.K. What is the final electron acceptor of the electron transport chain? Electrons in the chain are transferred from substrate to oxygen through a series of electron carriers.
