NEET Zoology (general) MCQ Question
Type: MCQ-numerical-Easy-Class 11
If a neuron has a resting potential of -70 mV and upon stimulation, the Na+ influx causes the membrane potential to reach +30 mV, what is the total change in the membrane potential?
A
100 mV
B
40 mV
C
70 mV
D
60 mV
Correct Answer
Option A
Detailed Explanation
The resting potential is -70 mV, and the action potential peak is +30 mV. The total change is the difference: +30 mV - (-70 mV) = 100 mV.
