ION Intracellular Conc. mMol Extracellular Conc. mMol
Na+ 10 142
K+ 140 4
Cl- 4 110
Ca2+ 0.0001 2.4
------------------------------------------------------
I realize that the OUTSIDE of a cell has a higher potential (+ charged). However, when I net the charges of the intra and extra-cellular environment, I see that the intracellular environment has "relative voltage" of 10 + 140 - 4 = +146.
For the extracellular Conc. is 142+4-110 + 2(2.4) = +41
Therefore, the INSIDE of the cell has more positive charges. Please explain why, in reality, the inside has a charge of -0.70 mV.
