Assertion : When carbohydrates are used as substrate and are completely oxidised, the RQ is equal to 1.
Reason : When proteins are used in respiration, the RQ is greater than 1.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion
B. If both assertion and reason are true but reason is not the correct explanation of assertion
C. If assertion is true but reason is false
D. If both assertion and reason are false

Answer

c

Explanation

The respiratory quotient upon the tupe of respiratory substrate used during respiration. When carbohydrates are used as substrate and are completely oxidised, the RQ will be 1. When proteins acts as respiratory substrates the value of RQ would be about `0.9`, i.e. (less than one).
