abstract::The P515 absorbance change upon single-turnover light flashes has been studied in intact leaves and isolated chloroplasts from spinach. A comparative study of the effects of preillumination on the kinetics of the P515 response and on the activity of the chloroplast ATPase has been made. The slow component (reaction 2)...

abstract::The ATP synthetase of chloroplast membranes binds ADP and ATP with high affinity, and the binding becomes quasi-irreversible under certain conditions. One explanation of the function of these nucleotides is that they are transiently tightly bound during ATP synthesis as part of the catalytic process, and that the rele...

The H+-dependent Ca+ efflux requires that either (a) the NAD(P)H pool of the mitochondrion be oxidized, or (b) the endogenous adenine nucleotides be depleted. The loss of Ca2+ is accompanied by swelling and loss of endogenou...
