Document Summary

Electrons in ground state don"t stay in that state they begin to fall bac towards ground state quite quickly. If they fall back to ground state the energy is released as a low energy photon or heat. 2 photosystems have the antenna complex that captures light and the reaction center. Once chlorophyll has excited its electrons they move towards the electron transport chain of photosynthesis. Energy released from chlorophyll a needs to be replaced. 2 electrons from water replace those proton concentration gradient and atp production: similar to that of cellular respiration. In cellular respiration nad+ is reduced to nadph. In photosynthesis nadp+ is reduced o nadph (important molecule) As electrons are moving protons are being transferred from the stroma to the thylakoid, making a concentration gradient, (powering atp synthase) (same as cellular respiration) Atp and nadph aren"t finished they"re going to move to the ---- calvin cycle.
