When the respiratory quotient is more than one then which respiratory substrates are not used?

• A. Pure protein
• B. Lipid
• C. Carbohydrate
• D. Both A and B

Answer 1

The correct option is D Both A and B

Respiratory Quotient $\left(RQ\right)$ is the ratio of the volume of $C{O}_2$ produced to the volume of $O_2$ consumed in respiration over a period of time. Its value for carbohydrate is $1$, for fats and proteins it is less than $1$, for succulent plants it is zero, for organic acids, it is more than one.
