Explanation of the correct option:
Respiratory quotient or respiratory ratio is measured by the volume of carbon dioxide released over the volume of oxygen absorbed during the respiration process.
The formula is given by:
It is a valuable measurement as it provides information regarding the nature of the substrate being used by an organism for respiration.
The values of RQ are:
RQ(carbohydrate)=1
RQ( lipid and protein)<1
RQ(anaerobic respiration)>1
Final answer: Respiratory quotient (RQ) is the ratio of CO2 produced to O2 consumed.
