Each ATP molecule contains about 1% of the amount of chemical energy available from the complete oxidation of a single glucose molecule. Cellular respiration produces about 38 ATP from one glucose molecule. What happens to the rest of the energy in glucose? It is stored as fat. It is converted to heat. It is used to make water from hydrogen ions and oxygen. It is released as carbon dioxide and water It is converted to starch.

Why does it take more oxygen to catabolism fat for energy than glucose?
