Respiratory quotient is represented as _______

Respiratory quotient is represented as _______

Options

A $\dfrac{\text{CO}_2\ \text{consumed}}{\text{O}_2\ \text{evolved}}$
B $\dfrac{\text{O}_2\ \text{released}}{\text{CO}_2\ \text{consumed}}$
C $\dfrac{\text{O}_2\ \text{consumed}}{\text{CO}_2\ \text{released}}$
D $\dfrac{\text{CO}_2\ \text{released}}{\text{O}_2\ \text{consumed}}$

Correct answer

D. $\dfrac{\text{CO}_2\ \text{released}}{\text{O}_2\ \text{consumed}}$

Step-by-step solution

Respiratory quotient (RQ) is defined as the ratio of the volume of carbon dioxide evolved (released) to the volume of oxygen consumed during respiration.

\text{RQ} = \dfrac{\text{Volume of CO}_2\ \text{released}}{\text{Volume of O}_2\ \text{consumed}}

Answer:

\dfrac{\text{CO}_2\ \text{released}}{\text{O}_2\ \text{consumed}}
