A germinating castor seed uses lipids as its primary respiratory substrate. How does the amount of CO2 evolved compare to the O2 consumed?
Q1. A germinating castor seed uses lipids as its primary respiratory substrate. How does the amount of CO2 evolved compare to the O2 consumed?
Answer: Less CO2 evolved than O2 consumed
Explanation: Lipids have an RQ of ~0.7, meaning less CO2 is evolved than O2 consumed; carbohydrates have an RQ of 1.0.
