The chemical structure of the K+ channel at its mouth…
““The chemical structure of the K+ channel at its mouth strips off the water shells surrounding K+. Thus, K+ becomes smaller than Na+ and can pass through the channel, whereas Na+ cannot do so.””
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
The K+ ion sheds its water shell and becomes smaller than Na+, allowing it to pass through the channel, whereas Na+ cannot.
In simple terms: K+ fits the channel after losing water; Na+ does not.
