Answer:

Active transport

Step-by-step explanation:

The pumping of sodium ions out of the cell into the environment where there is a lower concentration is achieved through active transport. Active transport is the movement of molecules or ions against a concentration gradient across living cell membranes with the utilization of ATP. Active transport takes place through carries located in the membrane.
