Quizplus · Accepted Answer

The respiratory quotient (RQ) is defined as the ratio of the volume of CO₂ produced to the volume of O₂ consumed during respiration. This ratio is affected by the type of substrate being metabolized (fats vs. carbohydrates) and can provide important information about energy metabolism. A value of 1.0 indicates that only carbohydrates are being metabolized, while a value of 0.7 indicates that only fats are being metabolized. The actual RQ value for a given individual can vary depending on their diet, activity level, and other factors.
