So, let's try another example here, and let's try a case now where instead of dealing with a neutral molecule we have an ion, so we have c n minus.

那么，让我们来试一下另外一个例子，这次不是一个中性原子,而是一个离子，氰离子。

now we're dealing with a lot of different atoms in the molecule, much more complicated than the initial case of the cyanide ion where we only had two.

现在我们要面对的分子中有很多不同的原子，比我们一开始只有两个,原子的氰离子复杂多了。

In the presence of this ligand, this molecule, it's open, it allows transport of this ion, when the ligand is gone it doesn't.

配体存在的情况下通道才打开,允许这些离子穿过,配体离开后,这些离子就不能通过了
