Der Einfluß von Natrium- und Kalium-Ionen auf die Photophosphorylierung beiAnkistrodesmus braunii

摘要

During short-time experiments (30 sec to 60 min) sodium ions stimulate the phosphate uptake and especially the32P-labelling of the organic TCA-soluble phosphate compounds up to 1,500 (K+=100). The labelling is maximally stimulated in the light and in the dark at concentrations of about 5×10-3mol/l Na+and at pH 8. Lithium ions stimulate32P-labelling in a similar but less effective way. In comparison, in the presence of potassium ions the32P-label decreases
