Exercise 8

H + /ATP ratio in photosynthetic bacteria
(Integrates with Chapters 20.) Calculate (in Einsteins and in kJ/mol) how many photons would be required by the Rhodopseudomonas viridis photophosphorylation system to synthesize 3 ATPs (Assume that the R. viridis F1Fo-ATP synthase c-subunit rotor contains 12 c-subunits and that the R. viridis cytochrome b/c1 complex translocates 2 H + /e -.)
