Document Summary
Pigments: absorbs photons of light, with the right wavelengths. Chlorophyll a is oxidized and donates e- to primary e- acceptor(reaction center complex) Chlorophyll b and carotenoids are accessory pigments: donates excitation energy to chlorophyll a via inductive resonance, both share a conjugated bond structure, alternating single and double bonds. Chlorophyll absorbs blue and red wavelengths most strongly. Chlorophyll and carotenoids work together to absorb photons during photosynthesis. Glass pris(cid:373), shows o(cid:374)es i(cid:374) (cid:373)iddle do(cid:374)"t do (cid:373)uch. Where this light is harvested is the increasing level of magnification. Thylakoid membrane is where the chlorophyll is located. Purple diamond is the primary electron acceptor(reaction center complex) Photosystem i: absorbs 700nm light waves (p700) P680 is the two special chlorophyll a molecules(make up reaction center), can get oxidized, all other chlorophylls cant give up their energy. E- in p680 raised from ground state to excite state-->p680* P680* oxidized to p680* by primary e- acceptor pheophytin{primary electron acceptor}(pheo)
