The concentration dependence of the uptake rate of Cs + in yeast at low pH is described by a cubic rate equation rather than by a quadratic rale equation. This points to the involvement of three sties in the translocation of Cs + across the yeast cell membrane. The possibility that one of the three sites is only apparent due to interaction of Cs + with the electrical double layer of the yeast cell membrane is also considered.
