A) volume of \[{{O}_{2}}/\]volume of \[C{{O}_{2}}\]
B) volume of \[C{{O}_{2}}/\]volume of \[{{O}_{2}}\]
C) volume of \[{{O}_{2}}/\]volume of \[{{N}_{2}}\]
D) volume of \[{{N}_{2}}/\]volume of \[C{{O}_{2}}\]
Correct Answer: B
Solution :
Respiratory Quotient is defined as the ratio of volume of carbondioxide evolved, to the volume of oxygen consumed per unit time per unit weight. \[RQ=\frac{Volume\text{ }of\text{ }C{{O}_{2}}\text{ }evolved}{Volume\text{ }of\,{{O}_{2}}\text{ }absorbed}\] The RQ depends upon the nature of the substrate, which is oxidized in respiration.| Substrate T | Value of RQ | Substrate | Value of RQ | |
| Carbohydrate | 1 | Anaerobic | \[\infty \] | |
