WebJan 3, 2024 · Osmosis across cellular membranes relies on the facilitated transport of water by aquaporins. The passive diffusion of water molecules, can be demonstrated with an artificial (e.g., dialysis) membrane. Water will cross such a membrane if solute concentrations are higher on one side of the membrane. WebCells use forms of desalination to regulate their osmotic pressure. One device used to do this is an aquaporin: Introduction to aquaporins Aquaporins in nature. Aquaporins are proteins contained in the membranes of bacteria, plant and animal cells. They allow the passage of water across the cell while holding back ions and other solutes.

WebAquaporins selectively conduct water molecules in and out of cells, while preventing the passage of ions and other solutes. However, there are some variants of aquaporins that transport small amounts of uncharged solutes, such as glycerol, CO2, ammonia and urea across the cell membrane, depending on the size of the pore.
