B) -65
C) 40
D) 65

Question

Quizplus · Accepted Answer

At the peak of the action potential, the intracellular environment is approximately +40mV, while the extracellular environment is approximately -70mV. Therefore, the difference between the two environments is approximately 110mV (40 - (-70) = 110).
