Na+-K+泵 ——实际上就是Na+-K+ATP酶，存在于动植物细胞质膜上，它有大小两个亚基，大亚基催化ATP水解，小亚基是一个糖蛋白.Na+-K+ATP酶通过磷酸化和去磷酸化过程发生构象的变化，导致与Na+,K+的亲和力发生变化.大亚基以亲Na+态结合Na+后，触发水解ATP.每水解一个ATP释放的能量输送3个Na+到胞外，同时摄取2个K+入胞，造成跨膜梯度和电位差，这对神经冲动传导尤其重要，Na+-K+泵造成的膜电位差约占整个神经膜电压的80%.若将纯化的Na+-K+泵装配在红细胞膜囊泡（血影）上，人为地增大膜两边的Na+,K+梯度到一定程度，当梯度所持有的能量大于ATP水解的化学能时，Na+,K+会反向顺浓差流过Na+-K+泵，同时合成ATP.
