Respiration: Aerobic Resapiration
10.2 Aerobic Respiration
Definition
- Aerobic respiration = breakdown of glucose in the presence of oxygen, releasing a large amount of energy.
- Takes place in mitochondria.
Equations
- Word equation:
Glucose + Oxygen → Carbon dioxide + Water + Energy - Balanced chemical equation:
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + Energy

Key Features
- Produces ~38 ATP per glucose molecule.
- Complete breakdown of glucose.
- Energy released used for movement, active transport, protein synthesis, etc.
Examples
- Humans: Continuous aerobic respiration for daily activities.
- Plants: Aerobic respiration in roots and leaves for energy.
Comparison To Anaerobic Respiration
- Aerobic: High energy yield, requires oxygen.
- Anaerobic: Low energy yield, no oxygen needed.
