Suppose that the concentration of Ca outside the cell is 10 and inside the cell is 0.1 mmol/liter. The Nernst equation at 20oC is: You set the membrane voltage at 58 millivolts using a voltage clamp, and measure membrane current. If Ca is the only ion crossing the membrane, you would expect to see: Group of answer choices 0 current positive charges flowing out of the cell the membrane potential becomes more positive positive charges flowing into the cell
