Why is external respiration breathing necessary for cellular respiration?
Understand the Problem
The question is asking about the relationship between external respiration (breathing) and cellular respiration. It seeks to understand why the process of breathing is essential for the cellular respiration that occurs in cells for energy production.
Answer
Inhaled oxygen is necessary for receiving electrons and hydrogen ions from the electron transport chain.
Inhaled oxygen is necessary for receiving electrons and hydrogen ions from the electron transport chain, essential for ATP production in cellular respiration.
Answer for screen readers
Inhaled oxygen is necessary for receiving electrons and hydrogen ions from the electron transport chain, essential for ATP production in cellular respiration.
More Information
Oxygen is essential for cellular respiration because it acts as the final electron acceptor in the electron transport chain, helping to produce ATP, which is vital for cellular functions.
Tips
A common mistake is confusing the role of oxygen with its role in glycolysis. Oxygen is not required for glycolysis but is essential at the later stage of cellular respiration, particularly in the electron transport chain.
