Document Summary
- excited e a) fluorescence (reemission of photons) b)resonance transfer (transfer of energy /w adjacent pigments c) redox rxns(pigments = oxi acceptor =red) Antenna complex moves e from b to rxn centre. C e from rxn center to e acceptor (pheophytin) (stroma has low [h+] thklakoid has high [h+]low ph. Pq transports e and h thylakoid lumen (creates h gradient) Ferrodioxin is oxidized and nadp reductase transers ion forming nadph. Cyclic =this pathway produces atp but no nadph also no o2 is produced since e- are recycled and there is no need for water splitting. Low light (increase chlorophyll) levels limit ps, excess can poison (photoinhibiton) 1) fixation (i. e. formation of a c-c bond: reduction (produces g3p used for sugars) requires atp and nadph at psi flows (via ferredoxin) to pq, then pc and back to psi. Neural animal function motor pathway fastest (begins in spinal cord ends at skeletal muscle)
