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