During an action potential,the membrane potential depolarizes all the way up to ______ mV.
A)0
B)-35
C)+35
D)-70

Question

Quizplus · Accepted Answer

During an action potential, the membrane potential depolarizes all the way up to approximately +35 mV. This is the peak of the action potential before it repolarizes and returns to its resting state at approximately -70 mV. Choice A (0) is incorrect as the membrane potential does not remain at 0 during an action potential. Choice B (-35) is incorrect as this is approximately the threshold for depolarization to occur, not the peak of the action potential. Choice D (-70) is incorrect as this is the resting membrane potential, not the peak of the action potential.
