Respiratory quotient is the amount of CO2 evolved by amount of oygen required for the breakdown of tge substrate. For fat the RQ value is less than 1 and is generally 0.7. This is because fat contains less number of oxygen atoms compared to organic acids.(RQ of organic acids>1]

During Anabolic respiration, O2 is consumed and CO2 is evolved
The ratio of Volume of CO2 evolved to the volume of O2 consumed in respiration is called RQ ( Respiratory quotient )
When Fat is used as respiratory substrate,
RQ < 1
eg :-
(Tripalmitin)
2(C51 H98 O6 ) + 145 O2 ===> 102 CO2 + 98 H2O + Energy
RQ = 102/ 145 = 0.7
