Hints
The ratio of the volume of CO2 evolved to the volume of O2 consumed in respiration is called as the respiratory quotient [RQ]. Calculate RQ when albumin is used as a respiratory substrate[see the given equation]:
C77H112N2O22S + 77O2 → 63 CO2 + 38 H2O + SO2 + 9 CO(NH2)2
C77H112N2O22S + 77O2 → 63 CO2 + 38 H2O + SO2 + 9 CO(NH2)2
