Pronunciation: [ɹɪspˈɪɹətəɹˌɪ kwˈə͡ʊʃənt] (IPA) 
The respiratory quotient (RQ) is a term used to describe the ratio of carbon dioxide produced to oxygen consumed during respiration. It is a measure of the efficiency of an organism's energy production process. There are several synonyms for the term respiratory quotient, including respiratory exchange ratio (RER), respiratory ratio, and respiratory coefficient. These terms are often used interchangeably in scientific literature. The RER specifically refers to the ratio of carbon dioxide produced to oxygen consumed during aerobic metabolism, while the respiratory ratio describes the same ratio regardless of the type of metabolism. The respiratory coefficient is a more general term that can refer to any ratio of respiratory gas exchange.
