As a result of an experiment following measurements were obtained from a cell:
intracellular Na+ concentration of 10 mM,
intracellular K+ concentration of 140 mM,
intracellular Cl- concentration of 5 mM,
intracellular Ca2+ concentration of 0.0001 mM,
extracellular Na+ concentration of 150 mM,
extracellular K+ concentration of 5 mM,
extracellular Cl- concentration of 120 mM,
extracellular Ca2+ concentration of 5 mM.
Using these values calculate equilibrium potential for Ca2+ ion in these cells. (RT/F = 26.7 mV, 37oC)
