Question

What is meant by RQ? when will the value of RQ be one and when it will be less than one ?​

Answer 1

Respiratory quotient is the ratio of the volume of carbon dioxide produced to the volume of oxygen consumed in respiration over a period of time. Its value can be one, zero, more than 1 or less than one.

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

Respiratory Quotient is 0.7, for proteins it is 0.8, and for carbohydrates it is 1.0.
