When respiratory quotient is less than 1.0 in a respiratory metabolism, it means that
Carbohydrates are used as respiratory substrate
Volume of CO2 evolved is less than volume of O2 consumed
Volume of CO2 evolved is more than volume of O2 consumed
Volume of CO2 evolved is equal to volume of O2 consumed
Respiratory quotient of substances -
RQ for Carbohydrates = 1
RQ for proteins < 1
RQ for Organic acids > 1
RQ for Succulents = 0
