Vedclass · Answer

(D) The correct answer is $D$. Respiratory Quotient $(RQ)$ is defined as the ratio of the volume of $CO_2$ evolved to the volume of $O_2$ consumed during respiration. $RQ = \frac{	ext{Volume of } CO_2 	ext{ evolved}}{	ext{Volume of } O_2 	ext{ consumed}}$. The value of $RQ$ depends entirely on the nature of the respiratory substrate being oxidized. For carbohydrates, the $RQ$ is $1.0$. For fats, the $RQ$ is less than $1.0$ (approximately $0.7$). For proteins, the $RQ$ is approximately $0.9$.
