Ques. 1NEET (UG) 2026

2(C51H98O6) + 145O2 102CO2 + 98H2O + energy The Respiratory Quotient (RQ) of a biomolecule used for respiration, as per the above equation would be :

  1. Less than 0.5
  2. Between 1.25 and 2
  3. 1.0
  4. Between 0.5 and 0.95

Answer

(4) Between 0.5 and 0.95

Solution

RQ = Volume of CO2 evolvedVolume of O2 consumed

The given equation is the oxidation of tripalmitin (a fat), so

RQ = 102 CO2145 O2

⇒ RQ 0.7

As per NCERT, fats have RQ less than 1, and 0.7 lies between 0.5 and 0.95.

∴ RQ is between 0.5 and 0.95.
