Botany-Respiratory Quotient
NEET Botany Respiratory Quotient MCQ Question
Type: MCQ-numerical-Hard-Class 11
If an organism uses proteins as its respiratory substrate and the complete oxidation of the protein results in the release of 70 mL of CO2 and the consumption of 100 mL of O2, what is the respiratory quotient (RQ) for the organism?
A
0.7
B
0
C
4
D
0.5
Correct Answer
Option A
Detailed Explanation
The respiratory quotient (RQ) is the ratio of the volume of CO2 evolved to the volume of O2 consumed. For proteins, if the CO2 evolved is 70 mL and the O2 consumed is 100 mL, the RQ is 70/100 = 0.7.
