You are recording from a funny-looking cell. You hold the cell at various voltages and record the size of the currents. The results are to the right. In these graphs, each line represents a current at a different given voltage. The top, "control" plot represents the current responses to the various voltages when the extracellular concentration of K+ was 5mM. The bottom plot represents the responses to the same voltages, but the extracellular concentration of K+ is now 20mM. Do these results indicate that this cell is permeable to K+? Justify your answer. (suggestion: 1-2 sentences) 20 mM K

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.
