Presentation Transcript

  1. Emerson: Enhancement effect Red drop effect Far-red light alone is insufficient in driving photosynthesis Accessory pigments ＞ 680 nm  Two photochemical complexes

  2. Z scheme distinct antenna pigments and photochemical reaction center NADH structure 96T oral exam

  3. p.140 cyclic e- flow ATP synthesis, no NADPH formation A0: a chlorophyll A1: a quinone Membrane bound Fe-S proteins Fd: a soluble ferredoxin FNR: soluble ferredoxin-NADP reductase Yz: a tyrosine residue of D1 Pheophytin (Pheo) Plastoquinones (QA and QB) Cytochrome b6f complex Plastocyanin (PC): a soluble Cu protein

  4. Chloroplast: contains its own DNA, RNA, and ribosomes 5 m Essay 7.1 (2006) A Novel View of Chloroplast Structure: dynamic

  5. Trends in Plant Science (02) 7: 183 2 NADPH, 3 ATP / 8 photons

  6. Stryer Light absorption vs. photoinducedcharge separation

  7. Reaction center chlorophyll excited e- is transferred to a secondary acceptor heat release re-reduced by a secondary donor A very rapid series of charge separation → capture light energy Photon → e- rearrangement in the reaction center → e- transfer photon energy → redox (e-) energy
