Question

A neuron is damaged in a way that doesn't allow its potassium ion gates to open. Which of the following would be directly affected?
Receiving a stimulus
Repolarization
Reaching the threshold
Depolarization

Answer 1

I think it would be option A

Hope this helps!

Answer 2

Answer:

Option B - Repolarization

Explanation:

The change in the membrane potential to a negative value just after action potential is known as repolarization phase.

In cell, the depolarization event allows sodium channel to open. The cell after a short period of time allows the event of repolarization. The repolarization event occurs due to outflow of K+ ions. Thus, a damaged neuron will prevent the repolarization event.
