Calculate the membrane potential of a neuron at standard temperature under each of the following conditions:
a. The concentration of sodium, potassium and chloride is the same on both the inside and the outside of the membrane.
b. The concentration of ions inside and outside the cell are as given below, but the relative permeability is the same for the three ions.
c. The concentration of ions inside and outside the cell are as given below, but the relative permeability of K is 100 times greater than that of Na+ and Cl-.
[Na+]o=150mM; [Na+]i=15mM;
[K+]o=5mM; [k+]i=100mM;
[Cl−]o=150mM; [−]i=13mM;
