Question

what is the final electron acceptor of the electron transport chain? nad+ hydrogen oxygen water

Explanation:

In cellular respiration's electron - transport chain, electrons are passed through a series of electron carriers. Oxygen has a high affinity for electrons and combines with hydrogen ions to form water. It is the final electron acceptor. NAD+ is involved in earlier stages of cellular respiration as an electron carrier. Hydrogen is not the final acceptor but is involved in the process. Water is the product of the reaction when oxygen accepts electrons.

Answer:

oxygen
