Description: We need to breathe, voluntarily or involuntarily, every few seconds to stay alive. Let's look at the respiratory system and learn how oxygen enters the bloodstream.

Question

What is the difference between aerobic and anaerobic respiration? Write the equations to show both the processes.

Accepted Answer

The differences between the anaerobic and aerobic respiration are as follows:

Features Anaerobic respiration Aerobic respiration

Definition The process in which the breakdown of food takes place in the absence of oxygen is called anaerobic respiration. The process in which the breakdown of food takes place in the presence of respiratory gas is called aerobic respiration.

Features Anaerobic respiration Aerobic respiration

End products The end products are lactic acid (in muscles) or ethanol (in yeast). The end products are carbon dioxide and water.

Features
Anaerobic Respiration Aerobic Respiration

Site of occurrence. Anaerobic respiration occurs only in the cytoplasm of the cell. Aerobic respiration occurs in the cytoplasm and mitochondria of the cell.

Features Anaerobic Respiration Aerobic Respiration

Equation
C₆H₁₂O₆ → 2C₃H₆O₃ (Lactic acid) + Energy

or

C₆H₁₂O₆ → 2C2H5OH (Ethanol) + 2CO₂ + Energy
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy (as ATP)
