Which of the following statements concerning oxidative phosphorylation is false? Group of answer choices: The electron transport chain generates an electrochemical gradient that drives the production of ATP. ATP synthase with fewer subunits in its c ring will produce more ATP per proton. A “loose” β subunit of ATP synthase becomes a “tight” site as it produces ATP. When the supply of NADH and QH2 (ubiquinol) decreases, ATP synthase produces more ATP.
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. (F=96.4 kJ/V mol) Route: NADH → (Fe-S)N-5,6 Coenzyme Q → Cytochrome c₁ → Cytochrome a3 ⇒ 0₂ Table 11.1 STANDARD REDUCTION POTENTIALS (E°') FOR SELECTED ELECTRON CARRIERS IN THE ELECTRON TRANSPORT SYSTEM Electron carriers NAD+ + H+ + 2e → NADH Complex I (NADH-ubiquinone oxidoreductase) Fe-S (N-1b) Fe-S (N-3,4) Fe-S (N-5,6) Complex II (succinate dehydrogenase) FAD + 2H+ + 2e → FADH₂ (enzyme bound)…
