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.,
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. (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).
