Document Summary

Use e from sun: photoautotrophs (figure 10. 2, use sunlight to make organic molecules form co2, producers, ex. Cyanobacteria, plants, multicellular alga, purple sulfur bacteria, unicellular eukaryotes: purple sulfur bacteria---> release sulfur not c02, heterotrophs, consumers, primary, secondary, tertiary, and quaternary consumers. Light is a form of electromagnetic e. ----->emit light (2) leave atom, captured by acceptor (a) occurs in photosynthesis. Used bacteria that seek out o2 to determine optimal for photosynthesis in a green alga. Step 1: photon absorption- photon hits pigment in ps 2, e passes along pigment molecules, excites ps 1: no electrons. Step 2: electron transfer- excited electron in ps2 transferred to primary electron acceptor. Step 3: h2o oxidation-p680 is an ectremelt stron oxidizing agent--> h2o is oxidized, electron transferred from h to ps 680+, h+ released into thylakoid space, ps 680+ reduced to ps860, 02 released as by product. Step 4: etc (cytochrome complex)- primary electron acceptor goes through aetc from ps860 to ps1.
