Unformatted text preview: from one electron carrier to another? 9) Purple bacteria use light to generate a proton gradient, draw a schematic demonstrating this cycle. What is this H+ gradient used for? 10) a) Convert the energy of red light (172 kJ/Einstein) to J/photon b) Convert the energy of a photon of blue light (400 nm) to kJ/Einstein. 11) True/False: Antennae and reaction centers are integral membrane proteins 12) The fact that antennae bacteriochlorophylls are so close together in pigment-protein complexes allows strong interaction of pi orbitals. As a result, excitation of the pigments is localized/delocalized . 13) Why is it advantageous for LHC-II of plants to contain carotenoids in addition to cholophylls?...
