A) Na⁺/K⁺- ATPase pumps sodium into and potassium out of cells across the basolateral membrane.
B) Na⁺/K⁺- ATPase pumps sodium out and potassium into cells across the basolateral membrane.
C) Na⁺/K⁺- ATPase pumps sodium out and potassium into cells across the apical membrane.
D) Na⁺/K⁺- ATPase pumps sodium into and potassium out of cells across the apical membrane.
