When do cells use active transport instead of passive transport?

• to move water molecules to the external environment in the same direction as the concentration gradient

• to transport nutrients from a high internal concentration out of the cell

• to diffuse oxygen across the cell membrane

• to transport nutrients from a low external concentration into a cell with a high concentration using ATP
