一些较大的分子（如葡萄糖）已不能通过膜上小孔进出细胞，需要在载体蛋白的帮助下才能跨膜运输。这种在载体蛋白质帮助下的跨膜运输称为载体运输。载体运输根据运输过程有无能量消耗分为协助运输和主动运输两种。
载体运输
网络释义
离子通道理论对了解神经和肌肉组织的功能十分重要 (二)载体运输(carrier transport) 1.机理:载体蛋白(内在蛋白)与溶质结合→载体—物质复合体→透过质膜→释放进胞内.

天然气分子不仅是迄今我们发现的浓缩度最高的碳能量载体，而且它们是流体，易于运输。
Gas molecules are not only by far the densest form of carbon energy we've ever discovered; they're also easy to transfer because they're fluid.

正如他们发表在自然材料杂志(Nature Materials)上的论文所述，通过授权纳米载体颗粒的交流能力，药物的运输成功率可以增加40倍。
As they report in Nature Materials, they believe that by granting nanoparticles the ability to communicate with one another, the success of drug delivery can be increased 40-fold.

按照Dr Bhatia 和 Dr von Maltzahnt的报告所说，最后的结果是一个效率40倍于单纯使用纳米载体颗粒的运输系统。
The result, Dr Bhatia and Dr von Maltzahn report, is a delivery system that is 40 times more effective than using nanoparticles by themselves.

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
