Oxygen is the final electron acceptor. Oxygen, with it's great electronegativity, pulls electrons through the electron transport chain where these electrons provide the motive force to pump protons into the outer lumen of the mitochondria. When these protons fall down their concentration gradient oxygen is there to pick then up with the electrons and form water.

Oxygen is needed for the final step of cellular respiration, which is the electron transport chain, because it is the final electron acceptor. Without oxygen, the electron transport chain cannot function properly, leading to a halt in the production of ATP through oxidative phosphorylation.

Oxygen is need in electron transport chain.O2 acts as last electron acceptor.
