What process is described here? A concentration gradient of H⁺ ions is created in the periplasmic space by actively transporting the ions across the membrane using the energy liberated when carrier molecules are oxidized.When the H⁺ ions pass through ATPase, enough energy is generated to add phosphate groups onto ADP molecules.

Question

Quizplus · Accepted Answer

The concentration gradient of H⁺ ions in the periplasmic space is created through active transport, which is a key feature of oxidative phosphorylation. Furthermore, the energy generated when these ions pass through ATPase is used to add phosphate groups onto ADP molecules, which is another hallmark of oxidative phosphorylation. Therefore, the best choice is D, oxidative phosphorylation. None of the other options involve the creation of an ion concentration gradient or the use of ATPase to generate energy for phosphorylation.
