WebSo the difference between a sodium potassium pump and an antiporter is that the sodium potassium pump uses energy directly from an ATP molecule while an antiport uses the energy of a electro-chemical gradient (created by a sodium potassium pump) to move other particles against their gradient.

Powered by ATP, the pump moves sodium and potassium ions in opposite directions, each against its concentration gradient. In a single cycle of the pump, three sodium ions are extruded from and two potassium ions are imported into the cell. tmj va rating
