Vedclass · Answer

(D) The Respiratory Quotient $(RQ)$ is defined as the ratio of the volume of $CO_2$ evolved to the volume of $O_2$ consumed during respiration.When respiratory substrates are poor in oxygen,such as fats and proteins,they require more oxygen for complete oxidation.Consequently,the volume of $O_2$ consumed is significantly higher than the volume of $CO_2$ evolved.Therefore,the $RQ$ value for such substances is always less than one (e.g.,$RQ$ for fats is approximately $0.7$ and for proteins is approximately $0.9$).

The value of $RQ$ when the respiratory substances are poor in oxygen is
