And when we talk about any type of ion channel, there are just tons of different kinds of ion channels, and you can characterize them in a few different ways.

而当我们讨论任何一种离子通道时，离子通道有非常多种，你可以用几种不同的方法来描述它们。

That change happens because something gets triggered in the membrane, and what gets triggered is a voltage gated sodium channel, which is shown here.

The one that's on the top here is called ligand-gated ion channel and an ion channel is a protein that sits in the surface of a cell.

最上面的这个叫作配体门控离子通道,离子通道是一类位于细胞表面的蛋白

And that's all that's big enough to pass through or small enough to pass through. And if we go up even just one row on the periodic table to potassium, what we actually see is now that it's going to be too large, and, in fact, a potassium solvated with one water molecule won't go through our channel.

就是这样刚好大到它通过,或者说刚好小到它通过,即使我们再沿着周期表往下走仅仅一行到钾离子，我们看到的就将是它的个头太大了，实际上，溶解于一个水分子的单个钾离子,不能穿过我们的通道。

In some cases it might be a ligand-gated ion channel.

有时受体可能是一个配体门控离子通道

It would generate an electrical signal because it would - you'd open the ion channel and you would ion fluxes and you would change the membrane potential in just the way I described for the action potential.

它会产生一个电信号,因为--,离子通道会打开,产生离子流,膜电位会改变,像我讲动作电位时那样

So, for example, if we look at sodium channels, and sodium channels are some of the particularly prevalent ones when we're talking about neurons, if you think about the cell membrane, and this little green cartoon is me trying to show a sodium channel here, and in this case, you can see that it's closed, such that no ions are getting through.

比如，让我们来看一下钠离子通道，钠离子通道是我们会经常遇到的几个之一,在讨论神经元的时候，如果大家想想细胞膜，而这个绿色的小示意图就是我用来表示,钠离子通道的，在这种情况下，大家可以看到它是关闭的，因此没有离子可以通过。
