In oxidative phosphorylation.... 1. Succinate contributes 2e- to Complex II and 2H+ to the mitochondrial proton gradient. 2. NADH in the matrix passes 2 e- to coenzyme Q via Complex I. 3. Complexes I, II, III, and IV each contribute to the matrix proton gradient. 4. O2 stabilizes the catalytically active conformation of Complex V. 5. Reversible protonation of c subunits leads to rotation of the Complex V gamma subunit. 6. Each β subunit can bind ATP tightly under the right conditions. 7. For every 3 protons that pass across the inner mitochondrial membrane, 1 ATP is produced. Choose all options that are true.
