Define RQ. What is RQ value for fats?

The ratio of the volume of carbon dioxide released to the volume of oxygen consumed in respiration in a specific length of time under standard temperature and pressure is known as the respiratory quotient (R. Q).

When fats are used as respiratory substrates, they are hydrolyzed into fatty acids and glycerol during seed germination.

The RQ of glycerol after complete oxidation is 0.86.

Because fatty acids have a lower oxygen content than CO2, they require more oxygen to complete oxidation. As a result, O2 absorption is greater than CO2 liberation, and RQ falls below unity.
