Question

people need oxygen to survive. what is the primary function of inhaled oxygen? it is the final electron acceptor in cellular respiration. it is added to acetyl-coa during the citric acid cycle. it is used to form water during glycolysis. it is converted to co₂ during cellular respiration. i dont know yet

Explanation:

• In cellular respiration, oxygen acts as the final electron acceptor. This occurs in the electron transport chain.
• During the citric acid cycle, oxygen is not added to acetyl - CoA.
• Glycolysis does not use oxygen to form water.
• Oxygen is not converted to \(CO_2\) during cellular respiration; \(CO_2\) is produced from the breakdown of organic molecules like glucose.

Answer:

It is the final electron acceptor in cellular respiration.
