Question 2:
Suppose that the concentration of K* outside the cell is 10 and inside the cell is 10 mmol/liter. The Nernst equation at 20°C is: Eion = 58 millivolts/z- [log10 ( ([Ion] out) [lonlin You set the membrane voltage at +58 millivolts using a voltage clamp, and measure membrane current. If K* is the only ion crossing the membrane, you would expect to see: positive charges flowing out of the cell O positive charges flowing into the cell O current the membrane hyperpolarizes (becomes more negative)
Suppose that the concentration of K* outside the cell is 10 and inside the cell is 100 mmol/liter. The Nernst equation at 20°C is: Eion = 58 millivolts/z- [10810 (1) [lon]in You set the membrane voltage at +58 millivolts using a voltage clamp, and measure membrane current. If K* is the only ion crossing the membrane, you would expect to see: positive charges flowing into the cell O positive charges flowing out of the cell O current O the membrane voltage becomes more positive
