The energy-independent K(+)-H(+)-exchange was measured in intact mitochondria and submitochondrial particles at different K(+)-concentration of the incubation medium. Correlation was found between H+-displacement and specific activity of monoamine oxidase. It is concluded, that the energy-independent K(+)-H(+)-exchange is localized in the outer membrane of mitochondria.
