Using the information shown in the image and the structural details of the K+ channel, answer and explain the following: A. Calculate the ratio (F1/F2) of the electrostatic force (F1) produced by the interaction between a K+cation and one O atom of a carbonyl in the selectivity filter, and the force (F2) between a Na+ cation and one O atom of a carbonyl in the selectivity filter. Use this ratio to explain why the channel is selective for K+ relative to Na+?
