Assertion: In living organisms, respiratory substrates are often more than one. Reason: Pure proteins or fats are never used as respiratory substrates.

Assertion : Glucose is favoured respiratory substrate. Reason : When glucose is used as respiratory substrate and is completely oxidised, RQ is 1.

Assertion :- Cells oxidise glucose and other respiratory substances not in one step, but in several small steps. Reason:- Oxidation in multiple steps enabling some steps to be just large enough such that the energy released can be coupled to ATP synthesis.
