Why is oxygen the final electron acceptor?
Understand the Problem
The question is asking why oxygen acts as the final electron acceptor in cellular respiration, particularly in the electron transport chain process. This involves understanding the role of oxygen in accepting electrons, thereby allowing the continuation of the electron transport chain and the production of ATP.
Answer
Oxygen allows for oxidative phosphorylation and prevents the electron transport chain from halting.
The final electron acceptor is oxygen because it allows for oxidative phosphorylation and prevents the electron transport chain from halting.
Answer for screen readers
The final electron acceptor is oxygen because it allows for oxidative phosphorylation and prevents the electron transport chain from halting.
More Information
Oxygen is highly electronegative, making it an excellent final electron acceptor in the electron transport chain, leading to the formation of water (H2O) and allowing for the continuation of ATP production.
Tips
Confusing the role of oxygen with other molecules in cellular respiration. Remember, oxygen's key role is as the final electron acceptor in the electron transport chain.
