Botany-Respiratory Quotient
NEET Botany Respiratory Quotient MCQ Question
Type: MCQ-diagram based-Medium-Class 11
Consider a diagram showing a closed system where a plant is undergoing aerobic respiration. The system measures the volume of oxygen consumed and carbon dioxide evolved. If the respiratory substrate is a lipid, which of the following is the most likely respiratory quotient (RQ) value shown by the system?
A
0.7
B
0
C
2
D
0.9
Correct Answer
Option A
Detailed Explanation
The respiratory quotient (RQ) depends on the type of substrate. For lipids, the RQ is typically less than 1, often around 0.7, because more oxygen is consumed than carbon dioxide is produced during their oxidation.
