That's Correct!
It's Wrong!
The respiratory quotient (R. Q.) is the ratio of the volume of CO2 produced to the volume of O2 utilized in the oxidation of foodstuffs. This ratio provides information about the type of fuel being oxidized by the body. A respiratory quotient of 1 indicates that carbohydrates are being primarily oxidized, while a ratio below 1 suggests that fats are being utilized. On the other hand, a ratio above 1 indicates that proteins are being metabolized. Therefore, the respiratory quotient is a useful measure to understand the metabolic processes occurring in the body during respiration.
