Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Choose the right about repolarization.
A
Occurs in the paranodes.
B
When potassium ions come out.
C
The axolemma charge becomes negative again.
D
When calcium ions enter the axon.
Explanation: 

Detailed explanation-1: -What happens during depolarization and repolarization? During depolarization the cell becomes less negative due to positive charges entering the cell. During repolarization the cell becomes more negative and returns to resting potential.

Detailed explanation-2: -Repolarization occurs when the K+ channels open and K+ moves out of the axon. This creates a change in polarity between the outside of the cell and the inside.
