Assume that frog muscle cell membrane is permeable to Na and K only. The membrane permeabilities for Na and K are Pna and Pk respectively.
At 16∘C, the resting membrane is -91 mV.
What is the ratio of permeabilities Pna/Pk?
For frog muscle, intracellular and extracellular concentrations of ions are:
Table entries have units of nM/I.
