A key process in metabolism is the transport of hydrogen ions (H+) across a membrane to create a concentration gradient. Explain which arrangement of hydrogen ions (unequal concentration or equal concentration) allows work to be done.

Description : A key process in metabolism is the transport of hydrogen ions (H+) across a membrane to create a concentration gradient. Explain which arrangement of hydrogen ions (unequal concentration or equal concentration) allows work to be done.

Last Answer : It is clear that an unequal concentration, not an equal one, would be the only possibility that work will be done; the unequal concentration of hydrogen ions would allow them to flow across the membrane and increase not only entropy but also work.
