oxygen
O2 ADDED: Not O2, but one atom of oxygen.
Oxygen, because it is highly electronegative.
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.
An organism takes in oxygen during aerobic respiration.
The inputs for aerobic respiration are glucose and oxygen. Glucose is broken down in a series of chemical reactions to produce ATP (energy), while oxygen is the final electron acceptor in the electron transport chain.
Oxygen is considered the ultimate electron acceptor in aerobic respiration. It accepts electrons at the end of the electron transport chain, forming water as a byproduct.
The ultimate electron acceptor in aerobic respiration is molecular oxygen (O2), which gets reduced to form water (H2O). The ultimate hydrogen ion acceptor is also oxygen, as it combines with hydrogen ions to form water.
Aerobic respiration requires oxygen to operate (whereas anaerobic respiration does not), and oxygen is the electron acceptor.
In aerobic respiration it is oxygen.
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.
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.
O2 ADDED: Not O2, but one atom of oxygen.
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....
