NEET Zoology (general) MCQ Question
Type: MCQ-numerical-Medium-Class 11
If the electrical potential difference across a resting plasma membrane is -70 mV, and depolarization leads to a reversal of polarity resulting in a potential difference of +30 mV, what is the change in electrical potential difference during depolarization?
A
100 mV
B
40 mV
C
30 mV
D
70 mV
Correct Answer
Option A
Detailed Explanation
The change in electrical potential difference during depolarization is the difference between the resting potential and the depolarized potential, which is -70 mV to +30 mV, resulting in a change of 100 mV.
