Respiratory Quotient
2(C₅₁H₉₈O₆) + 145O₂ arrow 102CO₂ + 98H₂O + energy
The Respiratory Quotient (RQ) of a biomolecule used for respiration, as per the above equation would be :
Solution
Related Formula
R.Q = Volume of CO₂ evolvedVolume of O₂ consumedCore Logic
From the given balanced chemical equation (which represents the oxidation of Tripalmitin, a lipid):
- Volume of CO₂ evolved = 102
- Volume of O₂ consumed = 145
Step 1: Final Conclusion
The value 0.7 lies strictly between 0.5 and 0.95. Lipids generally have an RQ of around 0.7.
Pattern Recognition
RQ for fats/lipids is always less than 1 (approx 0.7). The molecule is tripalmitin. Doing mental math: 102/145 is clearly > 0.5 and < 1.
