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 ...
