The endpoint of the respiratory chain is the final electron acceptor: oxygen.

If you are talking about the Electron Transport chain then the endpoint is the production of ATP from the electrochemical gradient that is produced, this action is carried out by a really amazing enzyme the FoF1 ATP synthase.
So basically the respiratory chain is slowly pulling energy out of the elctron carriers NADH and FADH2 by using multiple cytochrome complexes which result in pumping protons across the membrane and creating a really powerful gradient that drived the ATP synthase to combine ADP and inorganic phosphate to make lots of ATP.

Well, it's more of a system than a chain. A system that involves plants and animals, O2 to CO2 back to O2. But, in the end, the enpoint is global warming. Just ask Al Gore. The more you breathe, the more Brazilian Rainforests suffer from it.
