The following conditions must be true for active transport:
Concentration gradient-The concentration of substance must be higher outside the cell than inside the cell.Energy-Active transport requires energy in the form of ATP.Transport proteins- It allows specific transport proteins such as pumps to facilitate movement of substance across the cell membrane.Overall, active transport allows cells to bring in substances that they need even if the concentration of those substances is low outside the cell.
