In aerobic respiration it is oxygen.
O2 ADDED: Not O2, but one atom of oxygen.
NAD+ is the first electron acceptor in cellular respiration (O2 is the final acceptor).
In aerobic respiration, the final electron acceptor is molecular oxygen O2. With anaerobic respiration, the final electron acceptor is a molecule other than oxygen, such as an organic substance.

Oxygen is required to live without it we die
In aerobic respiration, the final electron acceptor is (usually) oxygen. Sometimes it can be sulfur or nitrogen in the absence of oxygen (as in extreme environments) in extremophiles.
Oxygen, because it is highly electronegative.
Aerobic respiration - final electron acceptor is oxygen (O) Anaerobic respiration - final electron acceptor can besulfate (SO42-), nitrate (NO3-), sulfur (S), or fumarate....
The final electron acceptor in aerobic respiration is oxygen, which turns into H20.
The final acceptor of hydrogen in cellular respiration is oxygen. Oxygen combines with hydrogen to form water in the electron transport chain of the respiration process.
oxygen
Water. Oxygen is the final electron acceptor and also picks up two hydrogens at the end of the electron transfer chain to form water. H2O
