Abstract

SummaryActive chloride uptake by cells of Chara corallina decreases as the pH of the bathing solution is increased, using a range of buffers. Superimposed on this effect, large stimulations of Cl− uptake can be obtained by the addition of imidazole and tris buffers or ammonium sulphate. ‘Stimulated’ or ‘normal’ Cl− influxes respond similarly to the presence of metabolic inhibitors.It is suggested that these effects are not due to changes in photosynthesis or respiration, but reflect the dependence of Cl− transport on the pH gradient across the plasmalemma. Possible ways in which Cl− transport might be linked to H+ or OH− fluxes are discussed. It is proposed that the pH gradient across the plasmalemma is controlled by charge‐separating reactions which produce an active H+ efflux, and that Cl− uptake is linked to OH− efflux by ion‐exchange reactions.The metabolic implications of this scheme are discussed in detail, with reference to previous work on Characean and other plant cells.
