Question

The respiratory quotient value of 0.7 is obtained for

• A. Anaerobic respiration
• B. Glucose
• C. Proteins
• D. Tripalmitin.
  

Answer 1

Answer: (D)

Tripalmitin.

Respiratory quotient is the ratio of the volume of carbon dioxide released and oxygen consumed in respiration.

Its value is as follows:-

• It is unity for carbohydrates as an equal amount of both gases is involved.
  
• It is less than 1 as oxygen consumed is more than carbon dioxide released that is about 0.7 and the same for protein 0.9.
  
• Its value is greater than unity as in carboxylic acid oxygen consumption is less than carbon dioxide release.
  
• In anaerobic respiration, no oxygen is required.
  

So the correct option is 'Tripalmitin'.
