The process that uses membranes to couple redox reactions to ATP production is known as Oxidative Phosphorylation.

Here are the steps involved in this process:

1. Electron Transport Chain: The high-energy electrons from NADH and FADH2 are transferred to oxygen through a series of electron carriers. These carriers are located in the inner mitochondrial membrane and they constitute the electron transport chain. As the electrons are transferred from one carrier to another, energy is released.

2. Proton Gradient: The energy released from the electron transport chain is used to pump protons (H+) across the inner mitochondrial membrane, from the matrix into the intermembrane space. This creates a proton gradient, with a higher concentration of protons in the intermembrane space than in the matrix.

3. ATP Synthesis: The protons in the intermembrane space flow back into the matrix through an enzyme called ATP synthase. This flow of protons provides the energy needed for ATP synthase to convert ADP into ATP.

4. Oxygen's Role: Oxygen acts as the final electron acceptor in the electron transport chain. It accepts the electrons and protons to form water. This is crucial because it ensures the continuation of the electron transport chain. If oxygen were not present to accept the electrons, the chain would stop and no ATP would be produced.

So, oxidative phosphorylation is the process that uses membranes to couple redox reactions to ATP production.
