The Respiratory Quotient (RQ) of glucose is

  • 0.5

  • 0.7

  • 1.0

  • 1.5


C.

1.0

Respiratory quotient or RQ is dimensionless number used in calculations of Basal Metabolic Rate (BMR). It is calculated by the amount of CO2 eliminated to the O2 consumed.

i.e.RQ = CO2 eliminatedO2 consumed

Formula for glucose (carbohydrate) is C6H12O6. Thus, On comparing number of molecules of O2 to the molecules of CO2. We have the ratio 1 to 1 since, the molecules of O2 and CO2 are same,

i.e. RQ = 66 (i.e. 1)

Hence, RQ for glucose is 1 and for fat is 0.7, more than 1 (i.e., 1.5 or more means anaerobic respiration is taking place).
