NEET Zoology (general) MCQ Question
Type: MCQ-numerical-Medium-Class 11
If the resting potential of a neuron's membrane is -70 mV and the depolarization results in a reversal of polarity with the inner side becoming +30 mV, what is the total change in electrical potential across the membrane?
A
100 mV
B
70 mV
C
30 mV
D
40 mV
Correct Answer
Option A
Detailed Explanation
The total change in electrical potential is calculated by finding the difference between the final potential (+30 mV) and the initial potential (-70 mV), resulting in a change of 100 mV.
