Question

Also write your name on the back of the last pag 1. In photophosphorylation, absorption of light energy in chloroplast "light reactions" results in A) absorption of CO2 and O2 B) absorption of O, and release of co C) hydrolysis of ATP and reduction of NADP D) synthesis of ATP and reduction of NADP E) all of the above CO. 2. Photosynthetic phosphorylation and oxidative phosphorylation appear to be generally similar processes ATP synthesis coupled to the transfer of electrons along an electron carrier chain. Which of the following is true of , both consisting both processes A) Both contain cytochromes and accessory pigments in their electron carrier chains. B Neither process has membrane bound complexes. Cy Both use oxygen as a terminal electron acceptor D Both provide the major route of ATP and NADPH synthesis E) Both involve using the energy of a proton gradient to drive the synthesis of ATP 3. In what order do the following five steps occur in the photochemical reaction centers? 2) Replacement of the electron in the reaction center chlorophyll 4) Passage of excited electron to electron-transfer chain 1-2-3-4-5 31) Excitation of the chlorophyll a molecule at the reaction center 1 3) Light excitation of antenna chlorophyll molecule 2 5) Exiton transfer to neighboring chlorophyl A) B) 3-2-5-4- C) 3-5-1-4-2 D) 4-2-3-5-1 E) 5-4-3-2-1 4. Which of the following regarding plant photosystems is FALSE?
