Assertion: Glucose is the favoured respiratory substrate.
Reason: When glucose is used as respiratory substrate it is completely oxidised and RQ is 1.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false
If both assertion and reason are false.
