Question

In anaerobic respiration, the microorganisms like yeast breakdown glucose (food) in the absence of oxygen to form alcohol and carbon dioxide, and release energy.

• A. True
• B. False

Answer 1

The correct option is A True

Respiration

1. Respiration is the process of release of energy by breaking down food molecules(glucose) that are stored in the body cells.
2. There are two types of respiration: Aerobic respiration and anaerobic respiration.
3. The cellular respiration that takes place in absence of oxygen is known as anaerobic respiration.
4. Cellular respiration in some lower microorganisms such as bacteria and yeasts takes place in absence of oxygen.
5. Anaerobic respiration in yeast produces ethanol, carbon dioxide and energy.
6. Anaerobic respiration in yeast follows the following equation :

C₆H₁₂O_{6 ⇢} C₂H₅OH + CO₂ + Energy.
(Glucose) (ethanol) (carbon dioxide) (ATP)

Final answer:
The given statement is true.
