Can water easily diffuse across the membrane

WebJan 7, 2024 · The molecules that can easily diffuse across cell membranes are usually small. For example, molecules such as oxygen and carbon dioxide and lipids. These can easily cross the cell membrane because the are non-polar, and are soluble in the lipid bilayer. Uncharged small molecules such as water can also cross the cell membrane. WebWater molecules, for instance, cannot cross the membrane rapidly (although thanks to their small size and lack of a full charge, they can cross at a slow rate). Additionally, while small ions are the right size to slip through the membrane, …
