Schematic presentation of regulation of PSI/PSII stoichiometry and electron
transport state. Shaded area in each circle indicates level of reduced state
of each component. Reduced PSII and oxidized PSI are photochemically inactive,
respectively, and large occurrence of such states causes low efficiency of
photosynthesis. PQ, plastoquinone; Cyt b6-f,cytochrome b6-f complex; PC,
plastocyanin.
