ALVEOLI are the very small air sacs where the exchange of oxygen and carbon dioxide takes place. CAPILLARIES are blood vessels in the walls of the alveoli. Blood passes through the capillaries, entering through your PULMONARY ARTERY and leaving via your PULMONARY VEIN.

Answer:
Electron transport chain
Explanation:
In all eukaryotes electron transport chain is located in the inner mitochondrial membrane where it serves as the site of oxidative phosphorylation (production of ATP) through the action of ATP synthase.
Electron transport chain consists of protein complexes that transfer electrons from donors to acceptors via redox reactions. As a result of electron transport, protons (H+ ions) are pumped across a membrane and electrochemical proton gradient is formed. Proton gradiend is used for the ATP synthesis.
