the permeability of the human erythrocyte to anions has been measured under conditions of net charge transfer : for cl ( - ) and hco ( 3 ) ( - ) ions , at 37 degrees c , this permeability is 5 orders of magnitude too small to account for the rate of the electroneutral anion exchange which is responsible for the chloride , or hamburger , shift.2 .
