Describe the movement of substances in the sodium potassium pump

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.

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.
