Plants have 2 linked photo systems in the thylakoid membrane of chloroplast. Photosystem 2 pass an excited electron through an electron transport chain to photosystem 1 to replace an excited electron passed to NADPH. The electron lost from photsystem 2 is replaced by oxidation of H2O.
-Depend on products of light reaction
EX) Chlorophyll a absorbs most strongly in the violet-blue and red regions of the visible light spectrum.
-Energy as a particle=photon
-most abundant protein
-most "important" protein
Produces more ATP and no NADPH
-2 reduced Fd+NADPH
-2oxidized Fd+NADPH (reduced NADPH)
Structure- variable but similar blueprint
structure - same stuff as primary cell wall except lignin
