Write out the Nernst and GHK equations, and explain the significance of each. Define equilibrium potential.
What will be an ideal response?
This is discussed in the "Electrical Signals in Neurons" section of the chapter. The Nernst equation is used to calculate the equilibrium potential for individual ions, while the GHK equation calculates the predicted resting membrane potential of a cell. The equilibrium potential is the voltage at which there is no net movement of a particular ion across the membrane, because the force of the concentration gradient is exactly balanced by the force of the electrical gradient.
