Question

Describe respiratory quotient.

Answer 1

Hey friends.

"The respiratory quotient (or RQ orrespiratory coefficient), is a dimensionless number used in calculations of basal metabolic rate (BMR) when estimated from carbon dioxide production. ... A value of 0.7 indicates that lipids are being metabolized, 0.8 for proteins, and 1.0 for carbohydrates."

I hope it is helpful for you.

Answer 2

Answer:

The ratio of amount of Carbon dioxide produced to the amount of oxygen consumed during complete oxidation of metabolic fuel is termed as Respiratory Quotient.

 RQ= moles of CO₂ produced /moles of O₂ consumed

Explanation:

Respiration involves the oxidation of respiratory substrates to release energy and Carbon dioxide. The ratio of amount of carbon dioxide to the amount of oxygen produced is not similar for all the respiratory substrate. For example, for carbohydrates respiratory quotient is 1, for proteins it is 0.8-0.9 and for fats it is 0.7.
