Without a terminal electron acceptor, the electrons of and would have nowhere to be released, and all of the enzyme complexes involved with the electron transport chain would be "saturated" with electrons and the entire electron transport chain would cease to function, halting production of ATP.

Nothing would happen, the electron transport chain would function normally.

The oxygen would not be able to interact with ATP synthase and thus ATP production would halt, however, the electron transport chain would continue to function normally otherwise.

A mitochondria would use an alternative terminal electron receptor such as nitrogen or carbon dioxide, the electron transport chain would continue to function.

The mitochondria would synthesize new complexes for the electron transport chain and ATP production would continue.
