Movement of water through aquaporins
Nettet30. des. 2016 · AQPs are generally known for their high permeability to water. However, their involvement in other cellular functions, including permeation of small molecules … NettetA specialized example of facilitated transport is water moving across the cell membrane of all cells, through protein channels known as aquaporins. Osmosis is the diffusion of water through a semipermeable membrane from where there is more relative water to where there is less relative water (down its water concentration gradient) ( Figure 3.1.5 ).
