The depletion of ATP triggers potassium channels on the membrane of muscle cells to open up, which allows potassium to moves down its electrochemical gradient and out of the cell.

ATP的消耗触发了细胞膜上钾离子通道的开放，使得钾离子顺电位差梯度移出细胞。

Keep in mind that potassium ions carry a charge, so the difference in concentration also leads to a difference in charge - establishing an overall electrochemical gradient across the cell membrane.

钾离子携带一个电荷，因此浓度的差异也导致了电荷的差异，建立了全面跨细胞膜的电化学梯度。

别忘了钾离子还带有一个电荷，所以不同浓度的钾离子会有不同的电荷量，这会建立全面跨细胞膜的电化学梯度。
