Aerobic respiration breaks down glucose completely, producing both waste products and energy.

Products

• Carbon dioxide (CO₂): Released as a waste gas, exhaled by the lungs.
• Water (H₂O): Produced at the end of the electron transport chain when oxygen combines with hydrogen.
• ATP (Energy): About 36–38 ATP molecules per glucose, used to power body functions.

The most important product is ATP, as it fuels all cellular activities.
