What does the respiratory quotient (RQ) represent?

Options

  1. AThe amount of ATP produced during respiration
  2. BThe ratio of the volume of CO2 evolved to the volume of O2 consumed
  3. CThe ratio of glucose to oxygen used in respiration
  4. 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 .
