Web18 Mar 2024 · Potassium movement in and out of cells is controlled mainly by Na + /K + ATPase. This a transmembrane pump which uses active transport to move 3 Na + ions out of the cell (extracellularly) and 2 K + ions into the cell (intracellularly) . WebPotassium is also able to move from the cell across the apical membrane. Experimental evidence suggests that this movement occurs primarily through a K + -Cl − cotransporter, although in some preparations there is also evidence for …
