Question

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

Explanation:

In cellular respiration, oxygen acts as the final electron acceptor in the electron - transport chain. This is a key step in aerobic respiration.

• Acetyl - CoA combines with oxaloacetate in the citric acid cycle, not with oxygen.
• Carbon dioxide is produced from the breakdown of pyruvate (from glycolysis) in the citric acid cycle, not from oxygen conversion.
• Water is formed in the electron - transport chain (using oxygen as the final electron acceptor), not in glycolysis.

Answer:

It is the final electron acceptor in cellular respiration.
