Question

Write the chemical equation of anaerobic respiration in yeast.

Answer 1

Anaerobic respiration:

1. The respiration which takes place in the absence of oxygen is known as anaerobic respiration.
   
2. The microorganisms like yeast break down glucose (food) into ethanol, carbon dioxide and releases energy.It is a type of cellular respiration that takes place in the absence of oxygen to produce energy.
   
3. Lower organisms such as bacteria and yeast use this type of respiration in an environment devoid of oxygen.
   
4. In other organisms, it occurs during heavy activities like physical exercise.
   

Reaction of anaerobic ​respiration in yeast:

• Glucose →ethanol + carbon dioxide + energy
• C₆H₁₂O_{6 $⟶$} 2C₂H₅OH + 2CO₂ + 2ATP.
