Respiratory Quotient
- During aerobic respiration, O2 is consumed and CO2 is released.
- The ratio of the volume of CO2 evolved to the volume of O2 consumed in respiration is called the respiratory quotient (RQ) or respiratory ratio
- The respiratory quotient depends upon the type of respiratory substrate used during respiration.
- When carbohydrates are used as substrate and are completely oxidised, the RQ will be 1, because equal amounts of CO2 and O2 are evolved and consumed.
- When fats are used in respiration, the RQ is less than 1. Calculations for fatty acid, tripalmitin, if used as a substrate is shown:
- When proteins are respiratory substrates the ratio would be about 0.9.
- When organic acids are used as the respiratory substrate, the R.Q is more than one.
