(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 diffusion)是最简单的一种运输方式它只要物质在膜的两侧保持一定的浓度差即可发生。它所需要的能量来自于高浓度相对于低浓度所含...
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....

Active Transport Requires ATP ENERGY to move particles into or out of cell Movement of particles from LOWER concentration to HIGHER concentration Endocytosis Exocytosis ENDOCYTOSIS Cell membrane encloses a vesicle filled with particles and absorbs it, BRINGING IT INTO the cell ...
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...
Passive transport definition is the movement of ions or particles from an area of high concentration to an area of low concentration. This process does not require energy. What are 3 examples of passive transport? Solutes migrate from an area of higher concentration to a region of lower concentr...
Passive Transport Some things are too big or won’t pass through the bilipid layer Transport proteins can let through if going with concentration gradient Facilitated diffusion Sugars, amino acids Passive Transport Active Transport Movement of materials through a membrane against concentration gradient Use...
The facility to transport water actively may be a common property of insects; the particular examples that are discussed in this chapter are free from the objection on grounds that complementary processes could have promoted the movement of water passively. The absorption of liquid water into the ...
Since their movement is downhill or along their concentration gradient, the process does not require metabolic energy (e.g. ATP) as opposed to active transport, another type of cellular transport that essentially requires ATP to move substances against their concentration gradient. The four major ...
