Point at which the ratio of K+ permeability to Na+ permeability (PK/PNa) is the greatest.
Correct Answer: F
Description: Point A: RMP ( memebrane potential is closest to the equilibrium potential of potassium ion) Point B: Threshold potential Point C: Due to Hodgkin cycle rapid Na+ influx from voltage gated channels Point D: Na+ permeability maximum Membrane potential is closest to Na+ equilibrium potential Ratio of (P Na+/ P K +) maximum Point E: Potassium permeability maximum Point F: Only K+ permeability, no Na+ permeability Ratio of ( P K + / P Na+) is maximum
