Without these two systems working in tandem, your body would cease to function. Primary active transport sets the stage, building up the "battery" of the cell. Secondary active transport then uses that battery to ensure nutrients like glucose and amino acids are absorbed efficiently, even when their levels are already high inside the cell.
Primary transport uses raw ATP energy to do the heavy lifting. active transport primary and secondary
Secondary transport uses the momentum of one molecule to push another. Without these two systems working in tandem, your
