What is repolarization?
the regaining of charges, opposite of depolarization
2
New cards
What is in charge of the repolarization of the cell membrane?
voltage gated K+ channels
3
New cards
Step 1
voltage gated K+ channels open, K+ rushes into cell
bc electrochemical gradient
increases negativity on inside, eventually returning to -70 mV
inside to more negative state
outside to more positive state
4
New cards
Step 2
continues for a while, little Na+ and K+ required for depolarization and repolarization of membrane
Na+/K+ pump always working, can return ions to og concentrations inside and outside of cell
