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
And an important thing to remember when we talk about resonance hybrids is that the structure it's not 1/2 the time this structure, and 1/2 of the time this structure, it's actually some combination or some average between the two structures.
而当我们讨论共振杂化的时候,有一件重要的事情需要牢记,那就是这种结构并不是,一半时间处于这种结构的状态,而另外一半时间又变成了这种结构的状态,它实际上是两种结构在,一定程度上的组合或者平均。
