In the oxidative phase of oxidative phosphorylation, electrons are passedfrom NADH and ultimately to molecular oxygen through an electron transport chain comprised of multipleredox centers. Assume that an electron is passed through the chain along the route shown below. Clearly, thereare steps missing, but we will skip those to emphasize the energetics of the electron transport. Calculate DEº'and DGº' for each electron transfer step and record the values in the table. The reduction potentials for each ofthe redox centers are given in table 11.1.
