How would you describe what happens in the electron transport chain?

The electrons carriers such as NADH, FADH2 are reduced during the glycolysis and citric acid cycle. These electron carriers donate electrons and protons to the electron carriers proteins engaged in electron transport chain. The final electron acceptor is oxygen, which yields water molecule. Thank you

The inner mitochondrial membrane contains a sequence of protein complexes and coenzymes called the electron transport chain, which helps move electrons from electron donors like NADH and FADH2 to electron acceptors like oxygen. When electrons move through the chain, energy is released and used to pump protons from the mitochondrial matrix into the intermembrane space, creating an electrochemical gradient that is used by ATP synthase to produce ATP through a process called oxidative phosphorylation. Oxygen acts as the terminal electron acceptor in the electron transport chain, combining with protons to form water.
