[Glucose induced transport of H+, K+ and lactate in the cells of Acholeplasma laidlawii].

Currents of H+ and K+ ions initiated under the effect of facultative anaerobe of A. laidlawii, valinomycin, nigericin and carbonyl cyanide chloride phenylhydrasone on the membrane are recorded by means of the system of cation sensitive electrodes. It is stated that during glucose transport a redistribution of H+ and K+ and lactate between the cellular content and the medium takes place. Preincubation of cells with 3-o-methyl-D-glucose essentially decreases the effect of induced ion transport. It is concluded that ion transport observed in the experiments with glucose is related not to glucose transport through the cell membrane but to the release of its metabolic products from the cells.
