The respiratory quotient (or RQ or respiratory coefficient), is a dimensionless number used in calculations of basal metabolic rate (BMR) when estimated from carbon dioxide production. ... A value of 0.7 indicates that lipids are being metabolized, 0.8 for proteins, and 1.0 for carbohydrates.

The ratio of volume of CO2 evolved to the volume of O2 consumed in respiration is called respiratory quotient(RQ).
RQ=VOLUME OF CO2 EVOLVED/VOLUME OF O2 CONSUMED
When CARBOHYDRATES are used as substrate and are completely oxidised,the RQ=1
When fats are used in respiration,the RQ is less than 1
When proteins are used in respiration,the RQ would be about 0.9.
