The Relative Efficiency of ATP Synthesis in Noncyclic versus Cyclic Photophosphorylation If noncyclic photosynthetic electron transport leads to the translocation of 7 H+/2e- and cyclic photosynthetic electron transport leads to the translocation of 2 H+/e-, what is the relative photosynthetic efficiency of ATP synthesis (expressed as the number of photons absorbed per ATP synthesized) for noncyclic versus cyclic photophosphorylation? (Assume that the CF1CF0-ATP synthase yields 3 ATP/14 H+.)

The chemical coupling hypothesis (substrate-level phosphorylation) failed to explain why mitochondrial membrane mustbe intact during ATP synthesis. How does the chemiosmotictheory account for this phenomenon?
Sonicating a suspension of mitochondria produces submitochondrial particles derived from the innermitochondrial membrane. These membranous vesicles seal inside out, so that the intermembrane space of themitochondria becomes the lumen of the submitochondrial particle. Explain (or diagram) the process of electrontransfer and oxidative phosphorylation in these particles. Assuming all the substrates for oxidativephosphorylation are present in excess, does ATP synthesis increase or decrease with an increase in the pH ofthe fluid in which the submitochondrial particles are suspended? Why?
