Question

The final electron acceptor in the electron transport chain is called?

Answer 1

"By the time the electrons reach the final electron acceptor in Complex IV, they have very little energy left and need to be removed entirely from the system (otherwise the entire system will back up and be halted). Complex IV finally gives its electrons to molecular oxygen (O2), the final or terminal electron acceptor. The reduction of oxygen (remember, accepting electrons is a reduction reaction) results in the formation of a water molecule from the oxygen.
