"WebHowever, there is a type of active transport referred to as secondary active transport. While cellular transportation systems are used to move molecules in this secondary form of transport, ATP is not used to do it. Instead, entropy and ion pumps are used to transport the molecules, and a difference in the chemical potential results. " - How is active transport different to osmosis
