wat do u understand by the respiratory quotient?

Respiratory Quotient:  The ratio of the volume of carbon di oxide produced to the volume of Oxygen used in a unit time is called respiratory quotient (RQ).

RQ = CO2 eliminated / O2 consumed

It varies with different foods utilized in respiration. For glucose, RQ is 1 (6CO2/6O2 = 1) for fats about 0.7 and for proteins about 0.85. The RQ indicates the type of food oxidized in the animal body during respiration.
