Main Differences between Aerobic and Anaerobic Respiration - QS Study
QS Study

Aerobic processes in cellular respiration can only occur if oxygen is present, Anaerobic processes do not use oxygen. Main Differences between Aerobic and Anaerobic Respiration:

Aerobic Respiration

  1. Oxygen: Require Oxygen
  2. Pyruvic Acid: Pyruvic Acid oxidized complletely.
  3. Production of ATP: From one molecule glucose there produces 38 ATP
  4. End products: From each molecule of glucose there produce 6 molecules of CO2 and 6 molecules of water.

Example: Glucose + Oxygen → Carbon dioxide + Water + Energy

Chemical Equation:  C6 H12 O6 + 6O2  →   6CO2 + 6H2 O + 2900 kJ/mol

Anaerobic Respiration

  1. Oxygen: Do not require Oxygen
  2. Pyruvic Acid: Pyruvic Acid oxidized incompletely
  3. Production of ATP: From each molecule of glucose there produces 2 ATP
  4. End products: From each molecule of glucose there produce 2 molecules of ethanol and 2 molecules of CO2, or only 2 molecules of Lactic acid. No water is produced there.

Example: Glucose → Lactic acid + Energy

Chemical Equation: C6 H12 O→ 2C3 H6 O3 + 120 kJ/mol
