Pregunta:
What is selectivity due to in the K+ channel
Autor: Rhianna BriantRespuesta:
Selectivity of K+ is due to a hydration compensation mechanism, rings of oxygen are placed to compensate for loss of K+ hydration shell but not Na+ hydration shell (Na+ is too small to fit into the ring) controlled by a gating mechanism, minor structural changes that serve to obstruct the entrance to the pore.
