[Ion currents in mitochondrial and liposome membranes induced by acid action]

It is shown that potassium ion yield from mitochondria observed under low pH of the incubation medium and at the addition of n-(N,N-di-2-Chloridethyl)aminophenylacidic acid and low concentrations of 2,4-dinitrophenol results from the formation of non-electrogenic (nigericyn-like) carrier. The data are obtained which show that under experimental conditions a weak electrogenic transport of ions is observed along with non-electrogenic ion transport in the membranes.
