The overall equation of aerobic respiration is C6H12O6 + 6O2 giving
Correct answer: A. 6CO2 + 6H2O + energy
- A. 6CO2 + 6H2O + energy
- B. C2H5OH + 6CO2 + energy
- C. 2C3H6O3 + energy only
- D. 6CO2 + energy only
Explanation
Complete oxidation of glucose yields six molecules each of carbon dioxide and water with the release of energy, largely captured as ATP. Alcohol and lactate appear only in the incomplete breakdown of anaerobic respiration.

About Cellular Respiration
Cellular respiration releases energy from glucose through glycolysis, the link reaction, the Krebs cycle and the electron transport chain, producing ATP. The pathway differs in oxygen availability: aerobic respiration uses oxygen and yields more ATP, while anaerobic respiration produces much less ATP and forms lactic acid in muscles or ethanol and carbon dioxide in yeast.
