Question

A typical value of resting membrane potential is ______.

Options

• −40 mV

• −60 mV

• −70 mV

• −80 mV

Answer 1

A typical value of resting membrane potential is −70 mV.

Explanation:

A neuron's resting membrane potential is around −70 mV. This signifies that the neuron's inner voltage is 70 millivolts lower than the outer voltage. There are more sodium ions outside the neuron and more potassium ions inside it while it is at rest.
