One classic example is the movement of glucose from the intestinal lumen to extracellular fluid by epithelial cells. Epithelial cells use primary and secondary active transport , often in conjunction with passive diffusion through ion channels , to produce transcellular transport across epithelial tissues .

2020-11-17 · Passive diffusion is the transport of a molecule across a lipid bilayer membrane according to its electrochemical potential gradient without the assistance of additional transporter molecules. This process can be studied in pure lipid membranes, although it is acknowledged that the properties of even relatively pure lipid patches in native membranes are altered by the high density of

Passive diffusion is a physico-chemical process, whereas in facilitated transport, molecules pass through the membrane via special channels or are translocated via carrier proteins. Both passive diffusion and facilitated transport, in contrast to active transport, follow a gradient, where facilitation merely lowers the activation energy for the
