The membrane capacitance of a cell is 1 µF/cm² and the concentration of ions inside and outside of the cell is about 0.5 M. Calculate the fraction of uncompensated ions on each side of the membrane required to produce 100 mV in a spherical cell with a radius of 25 μm. Capacitance of 1 µF/cm² => 10-6 uncompensated Coulombs of charge are eede on each side of a cm² membrane to produce 1 V across membrane. e = charge on electron = 1.6 x 10-19 C, Avogadro's number = 6.02 x 1023

Suppose that the concentration of CI outside the cell is 100 and inside the cell is 10 mmol/liter. The Nernst equation at 20°C is: Eton = 58 millivolts/z- [10810 (m)] [lonlin You set the membrane voltage at 0 millivolts using a voltage clamp, and measure membrane current. If Cl is the only ion crossing the membrane, you would expect to see: Onegative charges flowing into the cell negative charges flow out of the cell 0 current the membrane hyperpolarizes (becomes more negative)
