A neuron may produce another action potential in response to larger than normal depolarization during the
 
  a. absolute refractory period.
 b. relative refractory period.
 c. depolarization phase of the action potential.
 d. hyperpolarization phase of an action potential.

Question 2

The absolute refractory period occurs because
 
  a. the cell is hyperpolarized, requiring a larger than normal stimulus in order to form another action potential.
  b. it takes time for the sodium-potassium pumps to return ion concentrations to the normal resting state.
 c. only one action potential at a time can travel the length of an axon.
 d. sodium channels cannot reopen until the cell regains its resting potential.
