Question

2(C${}_{51}$H${}_{98}$O${}_6$) + 145O${}_2$ $\to$ 102CO${}_2$ + 98H${}_2$O + energy

What is the R.Q. of above reaction?

• A. 1
• B. 0.7
• C. 1.45
• D. 1.62

Answer 1

The correct option is B 0.7

The RQ or respiratory quotient is the way to calculate the basal metabolic rate determining the ratio of carbon dioxide eliminated/ oxygen consumed. The above reaction the RQ is calculated as 0.7 if the respiratory substrate is a protein of fat. In the given equation C${}_{15}$H${}_{98}$O${}_6$ is tripalmitin fatty acid. Thus, the correct answer is option B.
