In the biological world, oxygen is one of the most electronegative elements there is. In the ETC, electrons are passed down the various proteins and cytochromes in redox reactions. But the only way for this to work is if the next electron acceptor is more electronegative than the previous. This means that the last acceptor of electrons has to be the most electronegative. Most organisms use oxygen as the last electron acceptor, though sulfur and nitrogen can be used in extreme environments where there isn't sufficient oxygen.
Because of it's great electronegativity. Oxygen " pulls " the electrons down the electron transport chain and, together with the spent hydrogen, make water as useful waste of oxidative phosphorylation. Only fluorine has greater electronegativity than oxygen, but fluorine is poisonous to the body.
Oxygen is very electronegative compared to any other element so it tends to accepts electrons very easily.
ATP
Yes. Aerobic respiration produces carbon dioxide and water. Also, oxygen is the terminal electron acceptor
No, because the electron acceptor is what cates the electrons as the leave the electron transport chain, which is oxygen in aerobic respiration. Since aerobic respiration uses oxygen, and anaerobic fermentation is abest of oxygen, anaerobic fermentation cannot possibly use oxygen as respiration does.
Hydrogen ions are pumped across the mitochondria's inner membrane producing a concentration gradient
Yes it is in aerobic environments
Aerobic respiration requires oxygen to operate (whereas anaerobic respiration does not), and oxygen is the electron acceptor.
In aerobic respiration it is oxygen.
NAD+ is the first electron acceptor in cellular respiration (O2 is the final acceptor).

oxygen
The final electron acceptor in aerobic respiration is oxygen, which turns into H20.
Aerobic respiration - final electron acceptor is oxygen (O) Anaerobic respiration - final electron acceptor can besulfate (SO42-), nitrate (NO3-), sulfur (S), or fumarate....
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.
Because oxygen is the last electron acceptor in the electron transport chain, the electron transport chain makes aerobic respiration aerobic.
ATP
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.
Oxygen, because it is highly electronegative.
