Solution
Correct Answer:
=1
- Definition: The Respiratory Quotient (RQ) is the ratio of the volume of CO2 evolved to the volume of O2 consumed during respiration.
- RQ=Volume of O2 consumedVolume of CO2 produced
- Glucose Respiration:
- C6H12O6+6 O2→6 CO2+6 H2O+Energy
- Calculation:
- RQ=6 moles of O26 moles of CO2=1.0.
- Others: Fats and proteins have an RQ<1 (because they are less oxygenated), while organic acids can have RQ>1.
This easy difficulty biology question is from the chapter plant physiology, covering the topic of respiration: rq. It appeared in the 2025 exam.
