Question

The ________________ quotient is calculated by dividing the amount of CO2 created and O2 utilized at rest or during exercise. This value indicates the relative contributions of fat and carbohydrate to total energy expenditure.

Answer 1

The respiratory quotient (RQ) measures the ratio of CO2 produced to O2 consumed. It indicates the relative contributions of fat and carbohydrate to total energy expenditure.

Step-by-step explanation:

The respiratory quotient (RQ) measures the ratio of the volume of carbon dioxide (V.) produced by an individual to the volume of oxygen consumed (Vo). RQ=[Vc/Vo]. This quotient provides information about the relative contributions of fat and carbohydrate to total energy expenditure. For example, an RQ of 1 indicates that glucose is the primary fuel source, while an RQ below 1 suggests that fat is being predominantly used.
