Abstract
The effect of Mg2+ on the light-dependent reduction of NADP by an artificial electron donor was investigated with isolated broken [pea] chloroplasts. In both short and long wavelength actinic light, addition of the salt under most conditions stimulates the yield and the saturation rate. The magnitude of the stimulation is a function of pH. The data indicate that previous interpretations of the Mg2+ effect in this system invoking changes in the spill-over rate between the photosystems is no longer tenable. Possibly addition of the salt causes activation of inactive reaction centers.Keywords
