Electron Transport and Oxidative Phosphorylation Practice Problems Reading Chapter 18 End of the chapter questions 1(a - d), 4, 5, 8, 14, 15, and 22 Then try these: 1. Explain the difference between oxidative phosphorylation and substrate-level phosphorylation. Both processes are used for ATP synthesis during the catabolism of glucose (and fatty acids). Oxidative phosphorylation uses the potential energy in a proton gradient (proton-motive force) to power the synthesis of ATP from ADP and Pi (catalyzed by the ATP synthase), and requires O 2 . Substrate-level phosphorylation occurs when phosphoryl groups are transferred from a molecule with a high phosphoryl transfer potential to one with a lower phosphoryl transfer potential (e.g. from PEP to ADP in the last reaction of glycolysis). 2. A. Calculate the value of Δ E’ 0 for the reaction (use the standard reduction potentials from the table in your book) Succinate + FAD -> Fumerate + FADH 2 Δ E º' = ( E º' e- acceptor ) ( E º' e- donor
