O produced. If a hexose sugar is used as the substrate, the overall equation can be written as follows:
(8.1)C H O +6O 6CO +6H O6 12 6 2 2 2→ + energy
A low rate of respiration is desirable, for a lower rate lengthens the storage life. The ratio of the volume of CO
released to the volume of O
absorbed is termed the respiratory quotient (RQ) and is used to evaluate the nature of the respiratory process.
