Which is true about how are cells use oxygen? A. When oxygen is present pyruvate is converted to lactate which enters the citric acid cycle. The reduced coenzymes donate hydrogen ions and high energy electrons to the electron transport chain, and oxygen acts as the final acceptor of hydrogen ions and low energy electrons after the hydrogen ions have passed through ATP synthase. B. When oxygen is present pyruvate is converted to Acetyl CoA which enters the citric acid cycle....
