  • If volume of CO_(2) liberated during respiration is more than the volume of O_(2) used, then the respiratory substrate will be

    A
    carbohydrate
    B
    fat
    C
    protein
    D

    Assertion : Glucose is favoured respiratory substrate. Reason : When glucose is used as respiratory substrate and is completely oxidised, RQ is 1.

    R.Q. is maximum when respiratory substrate is

    R.Q. of 4 is obtained when respiratory substrate is

    Respiratory quotient (R.Q.) is defined as the ratio of a volume of CO_2 evolved to the volume of O_2 taken in during the respiration process. Value of R.Q. depends on the nature of respiratory substrate and to the extent to which this substance is broken down into simpler products. Which of the following situation will give us the R.Q. value as infinity when alcohol is produced?
