If R. Q. is less than 1.0 in a respiratory metabolism it would mean that

A

Carbohydrates are used as a respiratory substrate

B

Organic acids are used as a respiratory substrate

C

The oxidation of the respiratory substrate consumed more oxygen than the amount of `CO_2` released

D

The oxidation of the respiratory substrate consumed less oxygen than the amount of `CO_2` released

Text Solution

Verified by Experts

The correct Answer is:
C
The ratio of the volume of `CO_2` evolved to the volume of ` O_2` consumed in respiration is called respiration quotient.
It R.Q. is less than 1 then the volume of `O_2` consumed is more than `CO_2` evolved. It is found when a job is used in respiration, the R.Q. less than 1 about 0.7.
