Anaerobic respiration is a type of respiration that does not require oxygen. It can have several final electron acceptors, such as sulfate, nitrate, sulphur 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.


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....


How are steps of cellular respiration different when it is anaerobic respiration?

In anaerobic respiration, the final electron acceptor is an inorganic molecule other than oxygen, such as sulfate or nitrate, whereas in aerobic respiration, the final electron acceptor is oxygen. As a result, anaerobic respiration produces less ATP compared to aerobic respiration. Anaerobic respiration also produces byproducts like lactic acid or ethanol.


What waste molecule is formed in the final electron acceptor?

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


What molecule is the final electron acceptor at the end to the electron transport chain?

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.


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.


In cellular respiration the final electron acceptor is?

O2 ADDED: Not O2, but one atom of oxygen.


What substance does aerobic respiration use that anaerobic respiration does not use?

Aerobic respiration uses oxygen as the final electron acceptor in the electron transport chain, while anaerobic respiration does not require oxygen and uses other molecules such as nitrate, sulfate, or carbon dioxide.


What is the final electron acceptor in respiration?

In aerobic respiration it is oxygen.


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.


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 definition of an anaerobic respiration?

Anaerobic respiration is respiration without involving oxygen.It makes use of electron acceptors other than oxygen. Although oxygen is not used as the final electron acceptor, the process still uses a respiratory electron transport chain.Anaerobic respiration is not fermentation (which makes no use of an electron transport chain), which is another anaerobic process by which organisms obtain energy.
