Solution
The correct option is C Oxidation of the respiratory substrate consumed more oxygen than the CO2 released
Ratio of the volume of carbon dioxide liberated to the volume of oxygen absorbed during respiration is called respiratory quotient (RQ). When the amount of oxygen used and amount of carbon dioxide evolved are equal then the: Quantity of CO2 liberated = Quantity of O2 used
and
RQ value = Quantity of CO2 liberated/ Quantity of O2 used = 1
When more O2 is consumed than CO2 liberated then the RQ value is less than 1
When less O2 is consumed than the CO2 liberated then the RQ value is more than 1
