Short Answer
Assume the following permeability ratios and ionic concentrations in a cell:
PK:PNa:PCl = 1 : 0.03 : 0.1
Where K+ inside = 400 mM, outside = 20 mM
Where Na+ inside = 50 mM, outside = 440 mM
Where Cl- inside = 100 mM, outside = 560 mM
Set up, but do not solve, an equation to calculate the membrane potential at room temperature.
