vacuolar pH of Chara braunii

The intravacuolar pH of penultimate branchlet segments of Chara braunii Gm. was measured using intracellular antimony electrodes. This pH was shown to vary somewhat irregularly with extracellular pH and frequently to be so low that the entire vacuolar potential could be accounted for by the Nernst p...

Description
Summary:The intravacuolar pH of penultimate branchlet segments of Chara braunii Gm. was measured using intracellular antimony electrodes. This pH was shown to vary somewhat irregularly with extracellular pH and frequently to be so low that the entire vacuolar potential could be accounted for by the Nernst potential of hydrogen.
