Most cells have a resting membrane potential between
A)+60mV and -90mV.
B)-60mV and -90mV.
C)-65mV and -85mV.
D)+65mV and +90mV.

Question

Quizplus · Accepted Answer

The resting membrane potential is the voltage difference across the plasma membrane when a neuron is at rest. This potential varies among different types of cells, but in general, most cells have a resting membrane potential between -65mV and -85mV. Option A is incorrect because a resting membrane potential of +60mV is not physiologically possible. Option B is incorrect because a resting membrane potential of -60mV is not within the normal range of most cells. Option D is incorrect because a resting membrane potential of +90mV is too high and not within the normal physiological range.
