Hello all,
Good evening!
I have a quick question about membrane potential when I came across the following question:
Q: For most cells, extracellular calcium concentration is around 10,000 times higher than the intracellular calcium concentration. what is the membrane potential established by this electrochemical gradient?
A: V=(61.5/2)* log (10^4/1)= 123mV according to the Nernst equation.
I am just thinking why is the voltage inside of the cell positive 123mV when there is more Ca^2+...
