Another receptor eventually activates a phosphatase, that phosphatase now turns the protein off.

另一部分受体激活了磷酸酶,磷酸酶使这些蛋白失活

There are 100 of these molecules, when a receptor gets activated a kinase activity gets activated, the kinase acts on the protein, the protein gets switched on, something new starts to happen inside the cell.

有一百个这样的分子,当受体被激活,激酶被激活后,激酶作用于蛋白,使蛋白活化,细胞中就会发生一些新变化

When the ligand is present it binds to the receptor outside the cell and it activates this G-protein.

当配体存在并与细胞表面的受体结合时,就会激活G蛋白

It's called the G-protein coupled receptor because it's a receptor, like the one shown here, that's coupled to a special molecule called a G-protein.

之所以叫这个名字是因为这种受体,就像这里展示的一样,是与一种叫做G蛋白的特殊分子偶联的

It can also happen in other ways, it could be a G-protein coupled receptor which we talked about last time, which indirectly activates another ion channel to start the electrical signal.

还可以有其他方式,可以通过G蛋白偶联受体,这我们上次谈过,它可以间接激活,另一个离子通道以开启电信号
