[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.
