When one of the receptors encounters such a molecule, it relays a signal across the cell membrane that, in turn, initiates a response.
当一种受体与其相应的配体相遇,经细胞膜传递信号,随后启动下一个反应。
The redistribution of membrane receptors and proteins, caused by shear stress, is a vital step for cell migration, followed by chemical reactions and signal transduction.
在力学刺激作用下,内皮细胞发生形态学改变、表面受体重新分布,引起一系列化学变化和信号传导。
Modern pharmacological studies have shown that combination with some receptors or channels on cell membrane is the first step of drug action.
现代药理研究表明:药物发挥作用的首要步骤是与细胞膜上的某些受体或通道结合。
That general class of molecules is called receptors and its shown here just as a block of material living in the cell membrane.
这一类分子叫做受体,在这里看起来就像是,生活在细胞膜内的物质
Another characteristic of the synapse is that the post-synaptic membrane, the membrane of the cell which is going to receive the signal has receptors on it.
突触的另一个特征是,它们都有一个突触后膜,这个膜上含有受体,可以接受信号
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
