How does h2o move across the membrane

WebApr 21, 2024 · Small uncharged polar molecules, such as H2O, also can diffuse through membranes, but larger uncharged polar molecules, such as glucose, cannot. Charged molecules, such as ions, are unable to diffuse through a phospholipid bilayer regardless of size; even H+ ions cannot cross a lipid bilayer by free diffusion. WebWater transport across the cell membrane is an energy-independent process. It is popularly known as osmosis. It is a passive diffusion as it does not use energy. Aquaporins facilitate water movement through it. Water movement across …
