[Electrophoresis of chloride ions and changes in the membrane potential of energized mitochondria]

In energized rat liver mitochondria the simultaneous H+, K+ and C1- transport was studied by corresponding ion selective electrodes. It was shown that the C1- transport induced by valinomycin, by valinomycin plus carbonyclyanide m-chlorophenylhydrazone was governed by the membrane potential. It is suggested that observed in energized mitochondria the C1- electrophoresis may servt as an indicator of membrane potential changes.
