A Scientist Studying The Effect Of A Stimulus On A Motor Neuron

observed that the permeability of the plasma membrane to sodium ions (Na) and potassium ions (K) during the action potential. The graph in figure 2 represents the changes in membrane potential during an action potential. a.) Identify ONE difference between Na and K permeability curves shown in figure 1 b.) Describe ONE structural feature of the plasma membrane of the motor neuron that regulates the permeability of the plasma membrane to Na and K during an action potential c.) Connect the relative membrane permeability data shown with the changes in membrane potential during stages II and III of action potentials shown in figure 2.

a.) In figure 1, the permeability of the Na ions reaches a higher relative permeability in a quicker, but shorter amount of time compared to the K ions. b.) The axon terminal regulates the permeability of the plasma membrane to Na and K during an action potential. c.) The permeability of the membrane potential is the same as the ion permeability, except figure 2 shows the permeability beginning at at a lower threshold.
