    6. The membrane has open K+ channels, and changing extracellular K+ concentration results in a change in membrane potential. Changing the extracellular Na+ concentration does not significantly change the membrane potential. What do your results suggest about the number or state (open or closed) of Na+ channels in the resting membrane of a neuron?…

    C. Sodium conductance has a sharp spike (almost vertical line to a steady decline, reaching a top of approximately 0.034), however potassium (which peaks at 0.013) is a gentle rise and decline. Sodium conductance peaks at the same time as the membrane voltage. The potassium conductance begins to increase at about 0mV. The sodium conductance begins to increase at -34mV. Sodium movement is much higher at the beginning. Potassium is gradual from middle to end.…
