Document Summary
Chloroplast-inc sa of membrane which are known as thylakoid memb to capture more light photons. Described 3 processes: 1. ) e- goes back to ground state and all the energy emitted as heat thermal dissipatino 2. ) Fluorescence not conserved, also released as another photon of light, a lower e. 3>) Resonance transfer-e from one light going backt to ground state is inc e from molec"s in ground state to excited state. For as long as neighbor has potential to excitete the electron, then that chlorphyll molec can accept e thru resonance transfer. At this point, e trasnsferred not e- s yet. e- s stays in same moelc of chloryphyll. Then, when goes to ground state, e used to excite e- hopefully with neighboring. Reaction center chlorophyll when becomes excited, becomes e- donor. Can"t excite reaction center chlorophyll when doesn"t have e- to give off. Will get e- back from water, since water is e- donor.
