The primary kind of this process directly uses stored energy, while the secondary kind uses special proteins to combine two events: antiporters pair the motions of two ions, while symporters use ion diffusion to transport bulky molecules. The best known examples of this process occur with F-class proton pumps, notably involved in ATP synthesis, and P-class pumps, which include the sodium- potassium pump. For 10 points, give the term for all processes which move molecules across a cell membrane by consuming energy.
