1 ?钠离子通道 ...两心肌细胞膜的接合处,其主要功能是使离子快速通 过而将电流由一个细胞迅速地传至下一个细胞 (A)钠离子通道(sodium ion channel) (B)钾离子通道(potassium ion channel)..
- 1
An ion channel is a molecule that allows the passage of electrically charged atoms of sodium, potassium, calcium and so on through the outer membrane of a cell. 离子通道是一种分子，它允许钠、钾、钙等离子经由它通过细胞外膜。 - 2
However, when that gate is opened, the sodium channel is now going to be incredibly selective and only let through sodium ions and no other type of ion. 但是，当闸门打开的时候，钠离子通道，将会有极高的选择性，不允许除钠离子以外的任何其它离子通过。 - 3
Ion channel activity had the character of voltage-dependence. Some cells, which did not exhibit sodium currents exhibited, delayed rectifier potassium currents. 并且离子通道活动具有明显的电压依赖性，在没有记录到钠电流的细胞记录到延迟整流钾电流。
