73. How does the potassium channel maintain selectivity for potassium versus sodium ions? (MARK ALL THAT APPLY) Group of answer choices a. The partial negative charge of carbonyls in the pore is precisely balanced with the positive charge of only potassium ions. b. Potassium can form more interactions with the pore, resulting in desolvation of attached water. c. Sodium is too big to fit through the pore. d. Sodium can form more interactions with the pore, resulting in desolvation of attached water. e. On the basis of ionic radius.
