Question

The Respiratory Quotient (RQ) of glucose is

• A. $0.5$
• B. $0.7$
• C. $1.0$
• D. $1.5$

Answer 1

Answer: (C)

$1.0$

Answer 2

The Respiratory Quotient (RQ) is calculated as the ratio of the amount of CO2 eliminated to the amount of O2 consumed. It is a dimensionless number utilized in the calculation of Basal Metabolic Rate (BMR) which is as follows :
$RQ=\frac{CO_2\ \text{eliminated}}{O_2\ \text{consumed}}$
Thus, the RQ for glucose or carbohydrates is 1.0, for fats it is 0.7, for proteins it is 0.5, and for organic acids it is greater than 1.0.
So, the correct option is (C) : 1.0
