Action Potential In-Class Assignment 01/07/2021 The plot on the right-hand side is a conductance plot during a voltage clamp of a normal neuron. A voltage clamp is a procedure by which an experimenter applies a voltage to a cell and holds the cell at that voltage to observe the actions of cell components in a given electrical environment. The voltage applied to this cell is shown in the plot Vm. Also, shown during this voltage are the membrane conductance, or permeability, of sodium (gNa) and potassium (gk). gNa УК Vm 1. What is happening in the neuron membrane that causes the sodium conductance to rise when a voltage is applied to the cell? 2. What is happening in the neuron membrane that causes the potassium conductance to rise when a voltage is applied to the cell? 3. Why does sodium conductance rise before potassium conductance?

Draw the current that you would expect to flow during a voltage clamp experiment on a typical neuron. Voltages and time course are shown. Briefly explain why the currents are inward or outward. Be sure to provide scale bars. You should definitely label the Y axis so that the peak current value is obvious. Draw the Na+ current you would expect if there were physiological ionic gradients. Draw the K+ current you would expect if there are physiological ionic gradients. Draw the K+ current you would expect if the bath solution and the intracellular solution are both 125 mM.
