Scientists used microelectrodes to measure the resting membrane potential (inside relative to outside)of a typical neuron and discovered a difference of
A)70 mV.
B)300 mV.
C)-300 mV.
D)0 mV.
E)-70 mV.

Question

Quizplus · Accepted Answer

The typical resting membrane potential of a neuron is around -70 mV, with the inside of the neuron being more negative relative to the outside. This difference in charge is maintained by the activity of ion channels and transporters. Therefore, the correct choice is E (-70 mV).
