But we'll soon see when the commands you need to type become longer and more complicated, they just become annoying to type and annoying to remember so make generally automates this process for us.

They're very deep and held very tightly to the nucleus, so we can often lump them together and instead of writing them all out separately, 3s1 we can just write the equivalent noble gas that has that configuration.
它们非常深,被原子核吸得很紧，所以我们通常可以把它们混在一起,而不是把它们写开，我们可以写出氖然后3s1所以,或者任何的一个。

It's harder to find, they're more limited numbers, and in general, more difficult until eventually down this pathway you have fully differentiated cells, cells that are fully mature and performing the function of the mature organ.
不过找起来更困难,因为它们数量稀少而且通常很难定位,在分化的终末阶段,你可以看到完全分化的细胞,这些细胞完全成熟,在成熟的器官中发挥功能

For now, just picture it in this simple way as a molecule, usually a protein, that's embedded in the cell membrane and many receptors have a part of them that is extracellular.
现在,我只把这种分子图示出来,受体通常是一种蛋白质,它们镶嵌在细胞膜上,很多受体还有部分结构露在细胞外

Now, sodium and potassium don't ordinarily move across membranes, they're charged molecules, they can't dissolve, they can't permeate through a cell membrane, but they go through because there are channels that allow them to pass through in the membrane.
钠和钾通常是不能跨过细胞膜的,它们都是带电粒子,它们不能溶解在细胞膜中,不能渗透通过细胞膜,但它们之所以能通过细胞膜,全赖膜上离子通道的作用
-
I did want to say a little bit more about kinases because they're so important in intracellular communication and kinases take advantage of the fact that proteins can often exist in more than one state, and that's what makes them useful molecules inside cells.
关于激酶我想再多讲一点,因为它们对细胞内通讯十分重要,因为激酶的优越之处在于,这种蛋白通常不只有一种状态,这也令它们在细胞中的用处极大
