细胞膜是细胞与细胞外环境相连接部位的脂质双分子层,是转运离子和营养物质的媒介,具有接受信号分子,连接相邻细胞结构和细胞基质等功能。在真核细胞中,细胞膜的形态结构主要由细胞骨架来维持,同时细胞骨架也参与调控细胞膜功能活动如细胞吞噬、胞吐、跨膜信号转导等。作为细胞
Cell membrane is a lipid bilayer connecting cells to the extracellular environment. It is a mediator of transport ions and nutrients and has functions of accepting signal molecules, connecting adjacent cell structures and cell matrix. In eukaryotic cells, the morphological structure of the cell membrane is mainly maintained by the cytoskeleton, while the cytoskeleton is also involved in regulating the functional activities of the cell membrane such as phagocytosis, exocytosis, and transmembrane signal transduction. As a cell
