Question

Carbon dioxide is not produced by the oxidation of food during respiration.

• A. True
• B. False

Answer 1

The correct option is B False

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. During aerobic respiration, carbon dioxide, water and energy are produced by the oxidation of food molecules.
4. While anaerobic respiration mainly occurs in bacteria and microorganisms where carbon dioxide, ethanol and energy are released.

• .Aerobic respiration:
  • The process of liberation of energy during the oxidation of food molecules in presence of oxygen is known as aerobic respiration.
  • Aerobic respiration follows the following equation:

C₆H₁₂O_{6 +} O_{2 ⇢} CO₂ + H₂O + energy
(Glucose) (oxygen) (carbon dioxide) (water) (ATP)

• Anaerobic respiration:
  • The cellular respiration that takes place in absence of oxygen is known as anaerobic respiration.
  • Anaerobic respiration follows the following equation :

C₆H₁₂O_{6 ⇢} C₂H₅OH + CO₂ + energy
(Glucose) (ethanol) (ATP)
Final answer:
The given statement is false.
