Respiratory Quotient (RQ):

The respiratory quotient is a ratio that indicates the type of respiratory substrate being used during cellular respiration. It is calculated as the ratio of the volume of carbon dioxide (CO2) produced to the volume of oxygen (O2) consumed during respiration. The RQ value varies depending on the type of substrate being oxidized. For example:

  • RQ = 1: When glucose is the substrate, as in complete carbohydrate metabolism.

  • RQ < 1: When lipids (fats) are the substrate, indicating incomplete oxidation.

  • RQ > 1: In rare cases, such as in the metabolism of certain organic acids.
