What is the Difference Between Aerobic and Anaerobic Respiration? Complete Comparison

Respiration is the process by which living organisms break down food to release energy. It can be of two types – Aerobic and Anaerobic. Understanding the difference is very important for Class 10, Class 11 and NEET.

Difference Between Aerobic and Anaerobic Respiration

FeatureAerobic RespirationAnaerobic Respiration
Presence of OxygenRequires oxygenOccurs in absence of oxygen
SiteCytoplasm + MitochondriaOnly in Cytoplasm
End ProductsCO₂ + H₂O + EnergyEthanol + CO₂ or Lactic Acid + Energy
Energy Yield38 ATP (complete oxidation)Only 2 ATP (incomplete oxidation)
ExamplesMost plants and animalsYeast, bacteria, muscle cells (during heavy exercise)
Type of ProcessComplete breakdown of foodIncomplete breakdown of food

Aerobic Respiration Equation

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + Energy (38 ATP)

Anaerobic Respiration Equations

  • In Yeast: C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂ + Energy
  • In Muscle Cells: C₆H₁₂O₆ → 2C₃H₆O₃ (Lactic Acid) + Energy

Important Points for Exams

  • Aerobic respiration is more efficient as it produces more energy.
  • Anaerobic respiration in muscles causes fatigue due to lactic acid accumulation.
  • Fermentation is a type of anaerobic respiration.

Revise this comparison table thoroughly for board exams and NEET!
