Answer to Question 1

Answer: Voltage-gated ion channels of the axon membrane remain closed until the membrane potential reaches threshold (a fixed voltage). If the membrane potential reaches threshold, an
action potential occurs; if not, no action potential occurs.

Answer to Question 2

Answer: At rest, the interior of the axon membrane has more negative charges relative to the exterior. Movement of positive charges (sodium) into the axon results in the action potential (a
rapid reversal of the membrane potential).
