    Respiratory Quotient (R.Q.) is denned as :

    A)  \[\text{vol}\text{. of }{{\text{O}}_{\text{2}}}\text{/vol}\text{. of C}{{\text{O}}_{\text{2}}}\]

    B)  \[\text{vol}\text{. of C}{{\text{O}}_{\text{2}}}\text{/vol}\text{. of }{{\text{C}}_{\text{2}}}\]

    C)  \[\text{vol}\text{. of }{{\text{O}}_{\text{2}}}\text{/vol}\text{. of }{{\text{N}}_{\text{2}}}\]

    D)  \[\text{vol}\text{. of }{{\text{N}}_{\text{2}}}\text{/vol}\text{. of C}{{\text{O}}_{\text{2}}}\]

    Correct Answer: B

    Solution :

    During the process of aerobic respiration oxygen is consumed and carbon dioxide is released. Respiratory Quotient (R.Q) can be defined as the ratio between the volume of \[C{{O}_{2}}\]released and\[{{O}_{2}}\]consumed by the respiratory substrate \[R.Q.=\frac{VolumeofC{{O}_{2}}released}{Volumeof{{O}_{2}}consumed}\]
