Solution
The correct option is B Fats
Respiratory quotient is the ratio of the amount of CO2 eliminated to that of O2O2 consumed. Thus, it is evident that it solely depends on the nature of the substrate. For example, hexose sugar will have the value of R.Q = 1 because the volume of CO2and volume of O2stays the same. Fats have an R.Q less than one. There is consumption of more O2 than the carbon dioxide which gets eliminated and the organic acids will have their R.Q. values more than 1 because of the elimination of more CO2 molecules than the consumption of molecules.Thus, the correct answer is option B.
