Verified step by step guidance

Understand the function of ATP-driven pumps: These pumps use the energy from ATP hydrolysis to transport ions or molecules across membranes.

Identify the different classes of ATP-driven pumps: P pumps, V pumps, F pumps, and ABC transporters.

Learn about F pumps: F pumps, also known as ATP synthases, are unique because they can work in reverse. When operating in reverse, they use the energy from a proton gradient to synthesize ATP from ADP and inorganic phosphate.

Compare the function of F pumps with other pumps: Unlike P pumps, V pumps, and ABC transporters, which primarily use ATP to transport substances, F pumps can synthesize ATP when operating in reverse.

Conclude that F pumps are the class of ATP-driven pumps capable of synthesizing ATP when reversed, distinguishing them from the other classes listed.
