 Title    Mg2+-H + Exchange in Chloroplast Membranes in Dark  
 Abstract    Protons are released from unillum inated chloroplasts after the addition of Mg2+. The greatest num ber of protons was measured at pH 6.5 and corresponded to 0.6 mol protons per mol chloro­ phyll.

 Title    The Effect of M g 2+ on the Reduction of N A D P by an Artificial Electron D onor  
 Abstract    The effect of M g 2+ on the light-dependent reduction of N A D P by an artificial electron donor has been investigated with isolated broken 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. T he data indicate that previous interpreta­ tions of the M g 2+ effect in this system invoking changes in the spill-over rate between the photo­ systems is no longer tenable. It is suggested that addition of the salt causes activation of inactive reaction centers.
