electrogenic pump: An ion pump that generates a net charge flow as a result of its activity. Na+-K+ ATPase: An enzyme located in the plasma membrane of all animal cells that pumps sodium out of cells while pumping potassium into cells.

Why is it called an electrogenic pump?

Na⁺-K⁺ ATPase

It pumps three sodium ions out of the cell for every two potassium ions pumped in, leading to a net movement of one charge. Hence, the pump is electrogenic (i.e. it generates current).

What is meant by electrogenic pump?

Electrogenic pump. Definition: Electrogenic pumps are primary active transporters that hydrolyze ATP and use the energy released from ATP hydrolysis to transport ions across biological membranes leading to the translocation of net charge across the membrane.
