Expert Solution
Step 1 Concept introduction
Respiratory quotient (RQ) and Respiratory exchange ratio (RER) are two terms which look similar but they have a difference with their calculation and use. The RQ reflects the tissue substrate usage and RER reflects the exchange of carbon dioxide and oxygen. RQ helps to determine the basal metabolic rate and RER helps to determine the physical health of an individual. Let’s look RER in deep.
