WebAn open channel is highly selective; the permeability for K + may, for instance, be 1000–10,000 times higher than for Na +. The anion channel macroprotein for Cl − is very different from the cation channel protein of Na + or K +, for example (Jentsch, 2002). The selectivity is not due to ion size but to the charge spatial distribution in ... WebA selectively permeable membrane is one that allows only specific ions and molecules to pass through, while it obstructs the movement of others. Osmosis: It is the movement of solvent molecules from the region of lower concentration to the region of higher concentration through a semipermeable membrane.
