What substance is oxidized during cellular respiration?

water

carbon dioxide

glucose

oxygen

The overall chemical reaction of cellular respiration converts one six-carbon molecule of glucose and six molecules of oxygen into six molecules of carbon dioxide and six molecules of water ... So the carbons in the glucose become oxidized, and the oxygens become reduced.

glucose

Explanation:

During aerobic respiration, the oxygen taken in by a cell combines with glucose to produce energy in the form of Adenosine triphosphate (ATP), and the cell expels carbon dioxide and water. This is an oxidation reaction in which glucose is oxidized and oxygen is reduced.

C6H12O6 + 602 - > 6CO2 + 6H20 + energy in the form of ATP
