Question

What is the value of RQ for fats?

Answer in Brief

Solution

Its value can be one, zero, more than 1 or less than one.

RQ = `("volume of CO"_2 " evolved")/("Volume of O"_2 " consumed")`

RQ is less than one when the respiratory substrate is either fat or protein.

\[\ce{C57H104O6 + 80 O2 -> 57 CO2 + 52H2O}\]

RQ = `(57" CO"_2)/(80" O"_2)`

RQ = 0.71

RQ is about 0.7 for most of the common fats.
