细胞膜对物质的被动运输(passive transport)、主动运输(active transport)和膜泡运输各有何特点?相关知识点: 试题来源: 解析 (1)被动运输是物质顺浓度梯度从浓度高的一侧经细胞膜转向浓度低的一侧的运输方式它不需消耗细胞代谢的能量。被动运输又可分为简单扩散、通道扩散和协助扩散三种方式。 1)简单扩散(simple ...

Passive transport被动运输。不需要能量。又分为简单扩散simple diffusion (直接穿，比如脂肪与氧气）和易化扩散facilitated diffusion(需要蛋白质通道，比如葡萄糖）Active transport主动运输。需要能量。一般是逆浓度梯度。我的书上分为molecular transport,endocytosis and expocytosis....

名词:被动运输、主动运输、简单扩散、协助扩散、钠钾泵、协同转运、胞吞作用、胞吐作用 被动运输(passive transport):不消耗化学能,被运输物质顺着浓度梯度越过膜到达低浓度区域,不消耗生物能。 简单扩散(simple diffusion):无膜载体参与;不消耗能;运输速率与膜两侧浓度成正比,还与他们在水相与油相中的...

Both active and passive transport are the movement of molecules across the cell membrane, or concentration gradient, but there is a key distinction between active and passive transport. Active transport is the movement of molecules against the gradient, while passive transport is the molecular movement...
What is Active and passive transport Active:An Active transport in biology refers to the process by which molecules or ions are actively transported across a cell membrane against their concentration gradient, from an area of lower concentration to an area of higher concentration. ...
