NEET Zoology Nervous System Structure MCQ Question
Type: MCQ-numerical-Medium-Class 11
If a neuron maintains a resting potential of -70 mV and the threshold potential for action potential generation is -55 mV, what is the minimum depolarization required to reach the threshold potential?
A
15 mV
B
25 mV
C
10 mV
D
5 mV
Correct Answer
Option A
Detailed Explanation
The difference between the resting potential (-70 mV) and the threshold potential (-55 mV) is 15 mV, which is the minimum depolarization required.
