Which of the following best describes the cyclic electron transport carried out by purple photosynthetic bacteria?
A) Absorption of a photon by P960 leads to electron transport through a cytochrome bc_1 complex, then to a pool of quinones, and finally the reaction center is reduced through its quinonesB.) Absorption of a photon by P960 leads to electron transport through a cytochrome bc_1 complex, to a pool of quinones, then to a cytochrome c_2, and finally the reaction center is reduced through its quinones. C.) Absorption of a photon by P960 leads to electron transport through the reaction center quinones to a pool of quinones, to a cytochrome bc_1 complex, and finally the reaction center is reduced through its cytochrome c_2
Which best describers the relationship between photosynthetic reaction centers and light-harvesting complexes?
A) Light-harvesting complexes are needed by photosynthetic reaction centers only during episodes of dim light B.) Light-harvesting complexes absorb most of the photons, and pass the energy randomly among other such complexes until it reaches a reaction center C.) Each photosynthetic reaction center has one light-harvesting complex that directs the energy of absorbed photons to it.
