As the hydrolysis of CO2 continues, HCO3 − ions begin to accumulate in the erythrocyte. To maintain a consistent concentration across the cell membrane, some of these anions diffuse outward into the plasma. Because the erythrocyte is not freely permeable by cations, electrolytic equilibrium must be maintained by way of an inward movement of anions. This migration is achieved by _______________ from the plasma into the erythrocyte?
