Why does the respiratory quotient (RQ) equal 1 when carbohydrates are completely oxidized?
Options
- ABecause more O₂ is consumed than CO₂ is evolved
- BBecause equal amounts of CO₂ are evolved and O₂ are consumed
- CBecause CO₂ is evolved without O₂ consumption
- DBecause no CO₂ is evolved
Correct answer
B. Because equal amounts of CO₂ are evolved and O₂ are consumed
Step-by-step solution
The respiratory quotient depends upon the type of respiratory substrate used during respiration. When carbohydrates are used as substrate and are completely oxidized, the RQ will be 1, because equal amounts of CO₂ and O₂ are evolved and consumed, respectively,
