NEET Zoology (general) MCQ Question
Type: MCQ-numerical-Medium-Class 11
If the resting potential of a neuron is -70 mV and the depolarization at site A causes the potential to reach +30 mV, what is the total change in the membrane potential during depolarization?
A
100 mV
B
70 mV
C
30 mV
D
60 mV
Correct Answer
Option A
Detailed Explanation
The membrane potential changes from -70 mV to +30 mV, resulting in a total change of 100 mV (from -70 mV to 0 mV is 70 mV, and from 0 mV to +30 mV is another 30 mV).
