Question

R.Q. for glucose (carbohydrates) is

• A. 1
• B. 0.5
• C. 2
• D. 0.05

Answer 1

The correct option is A 1

The respiratory quotient (RQ) is the ratio of CO${}_2$ eliminated to the O${}_2$ consumed. Hence it is directly proportional to the amount of CO${}_2$ released. The reaction of respiration is shown in the image.

$RQ=\frac{ValueofC{O}_2}{Valueof{O}_2}=\frac{6}{6}=1$

Thus the correct answer is option A.
