O2
ADDED:
Not O2, but one atom of oxygen.
In aerobic cellular respiration, the final electron acceptor if oxygen.
The final acceptor is oxygen or O2.
Oxygen.
Oxygen.
Molecular Oxygen, otherwise known as O2.
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.
For animals, the final hydrogen acceptr in cellular respiration is
Oxygen, because it is highly electronegative.
NAD+ is the first electron acceptor in cellular respiration (O2 is the final acceptor).
Oxygen is required to live without it we die
Oxygen.
In cellular respiration, the final electron acceptor of the electron transport chain is half of a diatomic oxygen molecule. This molecule is then reduced when it gains two low-energy electrons attached to two hydrogens, making a molecule of water as a by-product of cellular respiration.
Molecular Oxygen, otherwise known as O2.
In aerobic respiration it is oxygen.
It is the final electron acceptor in anaerobic respiration
oxygen
Oxygen serves as the final electron acceptor in the transport system.It is the only oxidized agent strong enough to do this. Without oxygen, cellular respiration could not occur.
Cellular respiration requires a macromolecule to be broken down (usually glucose) and a final electron acceptor for the end of the electron transport chain (usually oxygen in most organisms). The reactants are a product of photosynthesis.
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 necessary for aerobic respiration only . It is not required in anaerobic respiration . Oxygen is final electron acceptor and it forms water at end of E.T.C.
