Type: MCQ-numerical-Easy-Class 11

If a neuron has a resting potential of -70 mV and during depolarisation the potential difference becomes +30 mV, what is the change in membrane potential?

A

100 mV

B

40 mV

C

30 mV

D

70 mV

Correct Answer

Option A

Detailed Explanation

The change in membrane potential is the difference between the depolarised potential and the resting potential, which is 30 mV - (-70 mV) = 100 mV.
