What does the respiratory quotient (RQ) represent?
Options
- AThe amount of ATP produced during respiration
- BThe ratio of the volume of CO₂ evolved to the volume of O₂ consumed
- CThe ratio of glucose to oxygen used in respiration
- DThe amount of heat released during respiration
Correct answer
B. The ratio of the volume of CO₂ evolved to the volume of O₂ consumed
Step-by-step solution
As you know, during aerobic respiration, O₂ is consumed and CO₂ is released. The ratio of the volume of CO₂ evolved to the volume of O₂ consumed in respiration is called the respiratory quotient (RQ) or respiratory ratio.
