Answer:
True
Explanation:
the K+ channel filters selects K+ ions more than Na+ ions because K+ ions can go through the filter along with water ions within nano seconds, whereas, Na+ ions bound to the sites within the filter and does not move within the channel in a nano second time scale. This rapid transport gradient of hydrated K+ ions makes it selectively permeable. Moreover, K+ ions has the capacity to accommodate itself around eight oxygen atoms in the central cavity but the Na+ ions interacts with four oxygen atoms and two water molecules instantly making significant ion-protein interactions. A dehydrated Na+ ion stabilizes itself with oxygen and decreases its chances of reaching the central cavity of K+ channel.
