Question

The respiratory Quotient (RQ) of glucose is

• A. 0.5
• B. 0.7
• C. 1
• D. 1.5

Answer 1

The correct option is C 1

Respiratory Quotient or RQ is calculated by the amount of $C{O}_2$ eliminated to the $O_2$ consumed. It is a dimensionless number used in calculations of Basal Metabolic Rate (BMR).
i.e $RQ=\frac{C{O}_{2}eliminated}{O_{2}consumed}$
Hence, RQ for glucose or carbohydrate is 1.0 and for fat is 0.7, for protein it is 0.5 and for organic acids it is more than one.
