Homework Statement
Have to determine permeabilities [tex]\alpha[/tex] and [tex]\beta[/tex] (PNa/PK and PCl/PK)
as well as internal concentrations of Na+, K+ and Cl-
I have calculated different membrane voltages according to the external concentration (when altering one ion, the other two were set to zero).
Homework Equations
Ki = {(A2 + 4Co2)1/2 + A}/2
ψ = (kT/q) ln (Co/Ki)
and GHK equation:
VR = kT/qln {Ko*+*αNao*+*βCli/Ki+*αNai*+*βClo}
The Attempt at a Solution
I am having trouble calculating the internal concentrations for K, Cl and Na. I have the membrane voltages and the concentrations between 0mM and 300mM in 5mM increments.
I think once I am able to calculate that, I might be able to figure out the rest.
Thanks
