Facilitated diffusion involves

WebFacilitated Diffusion Also called facilitated transport or passive-mediated transport, facilitated diffusion occurs when molecules or ions are processed through spontaneous passive transport. The ions and molecules are moved across a biological membrane through certain transmembrane integral proteins. Facilitated diffusion is a form of facilitated transport involving the passive movement of molecules along their concentration gradient, guided by the presence of another molecule – usually an integral membrane protein forming a pore or channel. Facilitated diffusion does not directly involve high … See more The driving force behind diffusion of fluids is simply the probability behind Brownian motion. All molecules have some degree of erratic, random movement, largely dependent on … See more Diffusion is ubiquitous across the biosphere. It is seen in the movement of air and water, and is a necessary force driving global weather patterns. Within living systems, the … See more A number of important molecules undergo facilitated diffusion to move between cells and subcellular organelles. See more
