Molecules of this protein aggregate into "purple patches" in the cell membrane .
此种蛋白质分子在细胞膜上聚集成“紫斑”。
A molecular mechanism for the active transport of ions or molecules across a cell membrane.
这些分子在细胞膜上延展,将信号从外界环境传递到胞内。
These molecules span the cell's membrane and transmit signals from the external environment to its interior.
I mentioned earlier, we thought about receptors as being these blocks and membranes but there are different families of receptors.
我之前讲过,我们把受体看做一类,固定在细胞膜上的分子,但受体有许多不同家族
All cell membranes have these channels within them, and under their resting conditions sodium is moving from outside to inside, potassium's moving from inside to outside.
所有细胞膜上都有这种通道结构,在静息状态下,钠从细胞外流向细胞内,钾从细胞内流向细胞外
It turns out that one of the places that's been very fruitful to look for proteins that differ between cell populations is on the surface of the cell.
而事实证明,寻找能鉴别细胞种类的,特定蛋白的最佳位置,是在富含蛋白的细胞膜上
