on the basis of observations that a23187 did not activate k loss from cells during rvi ( when the na/h exchange was functioning ) and that amiloride inhibited k/h exchange by swollen cells only when cells had previously been shrunk in the presence of amiloride , i concluded that na/h and k/h exchange are mediated by the same membrane transport moiety .
