Why it is necessary for oxygen to be the final electron acceptor in aerobic respiration?

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.

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.

What is the ultimate electron and hydrogen ion acceptor in aerobic respiration?
ATP
Does aerobic respiration produce carbon dioxide and water?
Yes. Aerobic respiration produces carbon dioxide and water. Also, oxygen is the terminal electron acceptor
Does anaerobic cellular fermentation use the same final electron acceptors as aerobic respiration?
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.
What happens when that final electron acceptor accepts electrons from the electron transport chain?
Hydrogen ions are pumped across the mitochondria's inner membrane producing a concentration gradient
Is oxygen a terminal electron acceptor?
Yes it is in aerobic environments
What is the electron acceptor in aerobic respiration?
Aerobic respiration requires oxygen to operate (whereas anaerobic respiration does not), and oxygen is the electron acceptor.
What is the final electron acceptor in respiration?
In aerobic respiration it is oxygen.
What is the terminal electron acceptor in aerobic cellular respiration?
NAD+ is the first electron acceptor in cellular respiration (O2 is the final acceptor).
What is the electron acceptor in aerobic cellular respiration?
oxygen
What is the finale electron acceptor in aerobic cellular respiration?
oxygen
What are the final electron acceptors in aerobic?
The final electron acceptor in aerobic respiration is oxygen, which turns into H20.
Why is the electron transport chain characterized as aerobic?
Aerobic respiration - final electron acceptor is oxygen (O) Anaerobic respiration - final electron acceptor can besulfate (SO42-), nitrate (NO3-), sulfur (S), or fumarate....
What are the final electron receptor molecules involved in anaerobic and aerobic respiration?
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.
What stages in the process of aerobic respiration make it an aerobic process?
Because oxygen is the last electron acceptor in the electron transport chain, the electron transport chain makes aerobic respiration aerobic.
What is the ultimate electron and hydrogen ion acceptor in aerobic respiration?
ATP
Why is oxygen nessecary in cellular respiration?
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.
The final electron acceptor of aerobic respiration is?
Oxygen, because it is highly electronegative.
