the anions -- scn- , clo4- , hso3- and i- ( 10-20 mm ) as well as 4-acetamido-4'-isothiocyanatostilbene-2.2'-disulfonate ( k0.5 = 14 microm ) blocked the atp-dependent generation of delta ph observed in the presence of cl- , while other anions tested ( f- , phosphate , bicarbonate , some organic anions ) were virtually without effect and did not support the h+ transport .
