SOLVED: Potassium ion channels facilitate diffusion because: the Kt ion doesnt have to lose its solvation shell upon entering the cell. b. the channel provides concentration gradient: resolvation of the potassium ion within the channel costs more than its desolvation: d. the channel decreases desolvation energy of the potassium ion by the selectivity filter the K" ion loses its solvation shell upon entering the cell:
