Question

Respiratory quotient (RQ) for complete oxidation of glucose is:

RankGuru · Accepted Answer

1. **Definition**: The Respiratory Quotient ($RQ$) is the ratio of the volume of $CO_2$ evolved to the volume of $O_2$ consumed during respiration.
   - $RQ = \frac{Volume \ of \ CO_2 \ produced}{Volume \ of \ O_2 \ consumed}$
2. **Glucose Respiration**: 
   - $C_6H_{12}O_6 + 6 \ O_2 	o 6 \ CO_2 + 6 \ H_2O + Energy$
3. **Calculation**:
   - $RQ = \frac{6 \ moles \ of \ CO_2}{6 \ moles \ of \ O_2} = \mathbf{1.0}$.
4. **Others**: Fats and proteins have an $RQ < 1$ (because they are less oxygenated), while organic acids can have $RQ > 1$.
