We've talked about one class of molecules, they're transporters that move molecules from inside to outside, or outside to in, that wouldn't ordinarily be transported through a cell membrane.

我们已经讲过一类这样的分子,它们是能够将分子从胞内运至胞外的载体,或者从胞外运至胞内,这个过程不是简单地穿过细胞膜

It could be that that signal is 'you need more glucose', and so the cellular response is to create more glucose transporters to bring more glucose into the cell.

这信号还可能是,"需要更多葡萄糖",细胞的反馈就是,产生更多的葡萄糖载体,将更多的糖分子输送进细胞

Eventually what happens is that glucose transport molecules which are expressed and stored inside the cell get shuttled up to the surface, so the cells permeability to glucose goes up and more glucose can come in.

最终的结果是那些已经表达,并储存于细胞中的能够运输糖的载体分子,穿梭到细胞表面,这样细胞对糖的透过性提高,更多糖分子进入到细胞内部
