Is pushed out of the cell (against its gradient).

) on one side of the membrane. This creates potential energy, like water held behind a dam. The Flow: As those ions naturally leak back across the membrane through a transport protein, they act as a "power source." The Hitchhiker: The transport protein uses the energy from the falling ions to pull a second molecule (like what is secondary active transport

💡 Think of secondary active transport as a "revolving door." One person (the ion) pushes through with great force, and their movement provides the energy to sweep a second person (the molecule) through at the same time. To help you visualize this further, Is pushed out of the cell (against its gradient)

To understand secondary active transport, you must first understand the concept of a "battery" within the cell. The Flow: As those ions naturally leak back

Transporters are classified based on the relative direction of the two moving substances: Active Transport - OpenEd CUNY
