Professor PC Thomas Classes · Answer

(b) : During aerobic respiration, $\mathrm{O}_{2}$ is consumed and $\mathrm{CO}_{2}$ is released. The ratio of the volume of $\mathrm{CO}_{2}$ evolved to the volume of $\mathrm{O}_{2}$ consumed in respiration over a period of time is called respiratory quotient (RQ) or respiratory ratio. $$ R Q=\frac{	ext { Volume of } \mathrm{CO}_{2} 	ext { evolved }}{	ext { Volume of } \mathrm{O}_{2} 	ext { consumed }} $$
