By pumping positively charged potassium and sodium ions out of the cell, the number of negatively charged ions inside the cells rises.
通过不断把带正电荷的钾离子和钠离子压出电池,电池内负电荷数量就会增加。
Two electrodes flanking the system of channels then create a voltage that pulls positively charged ions such as sodium in one direction and negatively charged ions such as chloride in the other.
