after replacing intracellular chloride with sulfate and treating cells with the anion transport inhibitor 4,4'-diisothiocyanostilbene-2,2'-disulfonate , exposure to valinomycin results in uptake of tetra [ 3h ] phenylphosphonium ion and stimulation of [ 9 , 10- ( 3 ) h ] oleic acid incorporation , but , because anion efflux is prevented , no decrease in cell volume occurs .
