To accomplish this, cells use a special ion transporter that exchanges the hydrogen ion for a potassium ion across the cell membrane.

为此，细胞运用特殊的离子转运体，跨细胞膜以1个钾离子交换1个氢离子。

To accomplish this, cells use a complex series of multiple ion channels, exchangers, and pumps to exchange hydrogen ions for potassium ions across the cell membrane.

为完成这一步骤，细胞利用了一种特殊的离子转运体，在细胞膜两侧进行氢离子和钾离子的交换。
