What is the Respiratory Quotient (RQ Value) During the Aerobic

Question

What is the respiratory quotient (RQ value) during the aerobic catabolism of a typical lipid?
A) 0.71
B) 0.83
C) 1.00
D) 21.1 J/mL O2

Accepted Answer

The respiratory quotient (RQ) is the ratio of CO2 produced to O2 consumed. For lipids, which require more oxygen for oxidation compared to carbohydrates, the RQ is typically around 0.71.
