What's the role of oxygen in cellular respiration? A. It accepts electrons and keeps the electron transport chain running. B. It breaks down carbon-based sugar molecules to release energy and forms carbon dioxide. C. It combines with hydrogen ions in sugar molecules to release energy and form water. D. It supplies electrons to the electron transport chain to keep it running.

Step 1
This process involves three stages: glycolysis, the Krebs cycle, and the electron transport chain. In the first two stages, glucose is broken down into carbon dioxide and water, and some energy is released. However, these stages do not involve oxygen directly. Show more…
