Page 3- Sodium potassium pump

Question 1

Sodium potassium pump

Answer 1

A carrier protein (involving active transport)

Question 2

What does it result in?

Answer 2

The pump moves 2 potassium into the cell for every 3 sodium it moves out of the cell.
This results in a net reduction of positive ions inside the cell hence RMP = -70mV (Polarised state)
