WebAn action potential is a brief change in membrane potential from positive to negative. c. An action potential is elicited by hyperpolarization. d. An action potential occurs when the cell's membrane potential reaches threshold. e. The level of depolarization is graded in proportion to the magnitude of the stimulus. d. WebThe membrane potential changes from a negative value to a positive value. What characterizes repolarization, the second phase of the action potential? View Available Hint (s) Once the membrane depolarizes to a peak value of +30 mV, it repolarizes to its negative resting value of -70 mV. the penuma® implant
