Question

As the electron transport carriers shuttle electrons, they actively pump _____ into the outer membrane compartment setting up a concentration gradient called the proton motive force.

Answer 1

The electron transport carriers actively pump hydrogen ions (H+) into the outer membrane compartment, setting up a concentration gradient called the proton motive force.

Step-by-step explanation:

The electron transport carriers actively pump hydrogen ions (H+) into the outer membrane compartment as they shuttle electrons, setting up a concentration gradient known as the proton motive force. This proton motive force is essential for the production of ATP through chemiosmosis.
