The correct answer isCarbon dioxide, water, energy.

  • In aerobic respiration, glucose breaks down into Carbon dioxide, water, energy.

Key Points

  • Aerobic Respiration:
    • The respiration which takes place in the presence of oxygen is known as aerobic respiration.
    • In this process, in fact, each glucose molecule is converted into two molecules of pyruvic acid by the process, called glycolysis.
    • Glycolysis takes place in the cytoplasm of the cell.
    • The pyruvic acid formed, releases energy with the formation of carbon dioxide and water.
    • C6H12O6+ 6O2→ 6CO2+ 6H2O + energy

Additional Information

  • Anaerobic Respiration
    • The respiration which takes place in the absence of oxygen is known as anaerobic respiration.
    • In this process, the respiratory substances are incompletely oxidized to carbon dioxide and alcohol.
