This isn't homework - just working through questions in my text. The question gives two concentrations of calcium ions inside and outside the membrane and asks to find the Nernst potential - ok no problem there.
Then it asks if the calcium ions are in equilibrium if the resting potential is 70mV. If they were in equilibrium, then
E = (RT/zF)(ln([outisde]/[inside])
But then, at calcium equilibrium, the ratio would be 1... ln(1) = 0 and there would be no potential... am I correct?
Thanks,
Mark
