In Order to Test the Hypothesis That the Rising Phase

question 13

Essay

In order to test the hypothesis that the rising phase of the action potential is caused by Na⁺ influx, researchers recorded the magnitude of the action potential when in a normal solution (like sea water) and then again after increasing the extracellular Na⁺ concentration. What do you predict will happen to the action potential with the increased extracellular Na⁺ concentration and why? Draw the action potential on Figure Q2-30. Figure Q2-30
