alleryThe respiratory quotient (RQ) of carbohydrate respiration is
A1.0 because CO2 evolved equals O2 used
B0.7 because CO2 evolved is less
C0.9 because of partial oxidation
DLess than 0.5 in all cases
Answer & Solution
Correct answer: A. 1.0 because CO2 evolved equals O2 used
Carbohydrate RQ = CO2/O2 = 1.0 (the equation gives equal moles).
Fats RQ is about 0.7 (more O2 needed for the H-rich substrate).
Proteins RQ is about 0.9.
