Document Summary
Primary electronic accepter: capable of excepting electrons and becoming reduced-> pass it on to the reaction center complex (redox reaction) Photosystem 2 (p680 best at absorbing 680nm wavelength. Photosystem 1 (p700 best at absorbing 700nm wavelength. Strikes the pigment molecule raising it to a higher energy level, this allows other molecules around and to share the boost in energy. Electrons from 680 electronic acceptor is given to a primary electronic septic. Enzyme catalyzes the splitting of water molecules into two electrons. Photo excited electron passes from the primary electronic accepter (ps. Electrons fall to a lower energy level and synthesize atp-> have an ion is pumped into the thylakoid space. Light energy passes through the ps1 and excites the electron of a chlorophyll a molecule. Cyclic electron ow: photo excited electrons can take an alternate path. No production of nadp h and no oxygen released.
