Describe the movement of substances in the sodium potassium pump

The concentration of Na + is greater inside the cell, and the concentration of K + is greater outside the cell.

The concentrations of Na + and K + are both greater outside the cell.

The concentrations of Na + and K + are both greater inside the cell.

The concentration of Na + is greater outside the cell, and the concentration of K + is greater inside the cell.

The Sodium-Potassium Pump. Active transport is the energy-requiring process of pumping molecules and ions across membranes "uphill" - against a concentration gradient ... It moves two potassium ions into the cell where potassium levels are high, and pumps three sodium ions out of the cell and into the extracellular fluid.
