WebJan 1, 2016 · When a membrane surface is put in contact with a fluid containing charged species, several chemical interactions take place such as acid/base dissociation, ionization of functional groups, adsorption of ions on the membrane surface, and/or the partial dissolution of the membrane material (Cavaco Morão et al. 2006 ). WebSurface area and thickness of the plasma membrane: Increased surface area increases the rate of diffusion, whereas a thicker membrane reduces it. Distance travelled: The greater the distance that a substance must travel, the slower the rate of diffusion. This places an upper limitation on cell size. A large, spherical cell will die because ...
Web1987), or changes in membrane surface area (Neher and Marty 1982). These changes can be global or local, for example, when cells grow dendritic branches or add or remove membrane due to endocytosis or exocytosis at a synapse. Cell capacitance may also change due to local membrane thickness variations at lipid rafts, which are ~10 % thicker … WebMembrane Surface Usually the membrane surfaces are negatively charged, which implies co-ions are repelled while counterions are attracted to it, leading to the formation of an …
