[Induction of hydrogen ion transport in mitochondrial membranes].

The system of ion transport in mitochondria induced with Brensted acids (H+-acids) was studied. It has been shown that an increase of the activity of hydrogen ions in the incubation medium (pH decrease) along with the earlier obtained [3--5] K+/H+ exchange brings about the appearance of the system of electrogenic transport of potassium ions in mitochondria. A synchronous functioning of the two systems indicated provides the electrogenic transmembrane transport of hydrogen ions through the mitochondrial membrane (Fig. 3, diagram 6). When studying the induction of ionic transport the data were obtained in favour of the concept that the induction resulted from conjugated oxidation and hydrolysis of lipids.
