Question 1 1 / 1 pts Which of these is not a characteristic of an action potential? Each normal action potential for a given cell type looks identical, depolarizes to the same potential, and repolarizes back to the same resting potential. An action potential at one site causes depolarization at adjacent sites, bringing those adjacent sites to threshold. If an excitable cell is depolarized to threshold in a normal manner, then the occurrence of an action potential is inevitable. On the...
