2 ( C ₅₁ H ₉₈ C ₆) + 145 O ₂ 102 CO ₂ + 98 H ₂ O + energy The Respiratory Quotient (RQ) of a biomolecule, used for respiration, as per the above equation would be :
Options
- ABetween 0.5 and 0.95
- BLess than 0.5
- C1.0
- DBetween 1.25 and 2
Correct answer
A. Between 0.5 and 0.95
Step-by-step solution
The respiratory quotient (RQ) is defined as the ratio of the volume of carbon dioxide evolved to the volume of oxygen consumed during respiration. From the given balanced chemical equation: Volume of CO ₂ evolved = 102 Volume of O ₂ consumed = 145 RQ = 102 145 0.7 The calculated value of RQ is approximately 0.7 , which lies between 0.5 and 0.95 . Answer: Between 0.5 and 0.95
