Solution:
Respiratory Quotients (RQ) 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 is one, zero, more than 1 or less than 0 . RQ slightly more than unity is found when organic acids are broken down as respiratory substrates under aerobic conditions.
For example, C6H6O5+3O2→4CO3+3H2O
(Malic acid) RQ=4CO2/3O2 or 1.3
