The Respiratory Quotient (RQ) of a biomolecule, used for respiration, as per the above equation would be :
- A Between \(0.5\) and \(0.95\)
- B Less than \(0.5\)
- C \(1.0\)
- D Between \(1.25\) and \(2\)
Answer & Solution
Correct Answer
(A) Between \(0.5\) and \(0.95\)
Step-by-step Solution
Detailed explanation
(A) Between \(0.5\) and \(0.95\)
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 \(=145\)
\(RQ =\frac{102}{145} \approx 0.7\)
The calculated value of RQ is approximately \(0.7\), which lies between
\(0.5\) and \(0.95\).
