In the process, it pumps three sodium ions against its electrochemical gradient to the outside of the cell, and it brings two of these potassium ions into the cell. So this is the same exact pump that was used to basically transport the glucose molecules into our cell. Now, as this takes place, the concentration of sodium inside the side of plasma decreases. Eventually, the concentration of sodium outside is greater than inside of the cell. At this point, the sodium on the outside begins to travel into the cell via this cotransporter membrane protein. At the same time that the sodium travels, it basically brings those amino acids with it into our cytoplasm.
