Taking Nernst for a test drive
Well, that was a lot of work, but we finally have a way of calculating the equilibrium potential based on the concentration gradient of an ion.
Let's give this equation a run for its money. Remember the typical cell? And remember that the cell's membrane is generally only permeable to potassium (K+)? So...
What is the Nernst potential associated with the potassium ion?
Bet you thought that was going to be harder... Let's try another one
What is the Nernst potential associated with the sodium ion?
