regulation of cyclic & non-cyclic via phsphorylation

 State 1 -  noncyclic electron flow
    in sunlight
    PSI & PSII both activated within
            stacked grana
    LHCII-complexed w PSII
    thus PSII & PSI function in
            parallel with linear e- flow
            makes ATP & NADPH.
 State 2 -  cyclic electron flow
    light excitation unbalanced
    LHCII is phosphorylated
    LHCII dissocaites from PSII
    LHCII diffuses to intergranal area
            & associates w PSI & LHCI
            thus light favors PSI &
            cyclic electron flow
                      ATP & no NADPH
