Explanation:

Respiratory substances are those substances or substrates which can be catabolised to liberate energy. This break down takes place due to oxidation of the substrate inside the cells of living beings. The most common respiratory substrate is glucose as it is readily metabolised sugar and commonly available also.

ANSWER

A respiratory substrate is a molecule from which energy can be liberated to produce ATP in a living cell. Glucose is not the only respiratory substrate. All carbohydrates, lipids and proteins can also be used as respiratory substrates. Respiratory Quotient (RQ) can be measured by the ratio of the volume of carbon dioxide evolved to that of oxygen consumed by an organism, tissue, or cell in a given time i.e, RQ = VCO

.

Here, from the above table infers that lipid and protein will have a lower RQ value than 1, since more oxygen will be needed to oxidize the fats and lipids then to oxidize the carbohydrates.
