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...
Types of Diffusion Diffusion across the cell membrane is eithersimpleorfacilitated. Simple diffusionFacilitated diffusion MechanismMolecules move directly across the membrane without the aid of a carrier proteinMovement occurs passively down a concentration gradient, however, the molecules require the help of...

Facilitated diffusion is the transport of molecules from the region of higher concentration to the region of lower concentration with the help of carriers.
Mechanical actions like vortexing, shaking or centrifuging are used to enhance molecular dispersal and diffusion to the cellular boundaries and to provide forces that can be helpful in disrupting cell–cell attachments. Conventional tissue dissociation can require hours of time and numerous instruments ...
(luminal domain + transmembrane region) and 5 mol% CE randomly distributed around it, we observed diffusion of CEs into the lumen of the seipin oligomer and subsequent interaction of the carbonyl group with residue S166 or S165 in the membrane-embedded α2-α3 helices (Fig.5C, D, ...
