Q
What happened during depolarization
A
Once the membrane potential reaches threshold, it causes voltage-gated sodium channels to open. Sodium ions rush in causing depolarization.
1
Q
What does sodium-potassium pumps what into and out of the cell
A
Pumps sodium out and pumps Potassium in through active transport
2
Q
What is happening in repolarization
A
repolarization refers to the change in membrane potential that returns it to a negative value just after the depolarization phase
