Define RQ. What is its value for fats? | NCERT solution | Class 11 Biology | Unit-14 Respiration in Plants

Q.10:- Define RQ. What is its value for fats?



The ratio of the volume of CO2 evolved to the volume of O2 consumed in respiration is called the respiratory quotient (RQ). The RQ for carbohydrates is 1. The RQ for fat and protein is less than 1.
For example: Calculations for a fatty acid, tripalmitin
2(C5H98O6) + 145O2 → 102 CO2 + 98 H2O
RQ = Volume of CO2 evolved/Volume of O2 consumed
= 102 CO2/145O2 = 0.7
