What is the final electron acceptor in the electron transport chain?
Oxygen
Nucleolus
Myosin
Animalia
The correct answer is: Oxygen
The final electron acceptor in the electron transport chain is oxygen because oxygen has a high electronegativity and a great affinity for electrons. This allows it to efficiently combine with the electrons and protons that have been transported by the electron carriers. This final step results in the production of water and allows for continued ATP production through oxidative phosphorylation. The other options, nucleolus, myosin, and animalia, are not involved in electron transport and are not electron acceptors.
