Question

how do potassium channels select the ion that can travel through the channel? group of answer choices membrane-spanning subunits concentration pore loop voltage

Answer 1

Answer:  Potassium channels allow K+ ions to easily diffuse through their pores while effectively preventing smaller Na+ ions from permeation. ... This selection process occurs at the narrow selectivity filter that contains structurally identified K+ binding-sites

Explanation:

Answer 2

• When the Potassium channels allow K+ ions to easily diffuse through their pores while effectively preventing smaller Na+ ions from permeation.
• Although when This selection is processed occurs at the narrow selectivity filter that contains structurally identified K+ binding-sites
• After that, The remarkable ability of the potassium channel to pass that is only potassium ions is accomplished by a selectivity filter at one end of the pore, as shown here from PDB entry 1k4c. when To pass through the selectivity filter, that is each potassium ion has to shed these water molecules.
