What is the RQ of glucose?

(a) The RQ (Respiratory Quotient) of glucose is 1 RQ is the ratio of the volume of $\mathrm{CO}_2$ produced to the volume of oxygen consumed in respiration over a period of time. $$\begin{aligned} & \mathrm{C}_6 \mathrm{H}_{12} \mathrm{O}_6+6 \mathrm{O}_2 \longrightarrow 6 \mathrm{CO}_2+6 \mathrm{H}_2 \mathrm{O} \\ & \mathrm{RQ}=\frac{6 \mathrm{CO}_2}{6 \mathrm{O}_2}=1\end{aligned}$$
