Inhibitors of the ATP/ADP antiporter suppress stimulation of mitochondrial respiration and H+ permeability by palmitate and anionic detergents [PDF]

, 1990
The action of ATP/ADP-antiporter inhibitors upon the uncoupling effect of palmitate, detergents and ‘classical’ uncouplers has been studied. The uncoupling effect was estimated by stimulation of succinate oxidation and of H+ permeability of rat liver ...
