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.
Respiratory quotient (RQ) is a measurement of the ratio between oxygen (O2) an organism intakes and carbon dioxide (CO2) the organism eliminates, expressed with the formula “RQ=CO2 eliminated/O2 absorbed.
