这种运输主要是细胞与环境间的物质交换,包括细胞对营养物质的吸收、原材料的摄取和代谢废物的排除及产物的分泌。如细胞从血液中吸收葡萄糖以及细胞质膜上的离子泵将Na+泵出、将K+泵入细胞都属于这种运输范畴。
当CO被你吸入,它会取代通过红细胞运输出入心脏的氧气。
The CO you inhale takes the place of the oxygen that's carried to and from your heart by your red blood cells.
阿司匹林似乎是通过阻止血小板将癌细胞运输到全身来减缓癌症的扩散。
The drug seems to slow the spread of disease by preventing cancer cells from being carried around the body on blood platelets.
可生物降解的聚合物材料形成组织形状,水凝胶(对细胞无毒)负责将细胞运输到结构中。
Biodegradable plastic-like (polymer) materials are used to form the tissue shape, and a water-based gel delivers the cells to the structure (the gels aren't toxic to the cells).
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.
