Isolated chloroplasts from spinach (1, 2) and wheat (3, 4) are capable of a dark phosphorylation at the expense of an unknown reactive, labile substance or state formed in an earlier period of illumination. This substance, XB (I), is optimally stable at low pH, where it may accumulate in the light to the equivalent of 1 mole of adenosine triphosphate for 8 moles of chlorophyll. Such high yields require the presence during illumination of a cofactor catalyzing cyclic electron flow (2). The… CONTINUE READING
