What event triggers the generation of an action potential?

Here is the answer for the question – What event triggers the generation of an action potential?. You’ll find the correct answer below

What event triggers the generation of an action potential?
a. The membrane potential must return to its resting value of -70 mV from the hyperpolarized value of -80 mV.

B. The membrane potential must hyperpolarize from the resting voltage of -70 mV to the more negative value of -80 mV.

C. The membrane potential must depolarize from the resting voltage of -70 mV to its peak value of +30 mV.

D. The membrane potential must depolarize from the resting voltage of -70 mV to a threshold value of -55 mV.

The Correct Answer is

D. The membrane potential must depolarize from the resting voltage of -70 mV to a threshold value of -55 mV.

Reason Explained

D. The membrane potential must depolarize from the resting voltage of -70 mV to a threshold value of -55 mV. is correct for What event triggers the generation of an action potential?
