In which of the following, R.Q will always be less than one?
Options
- APotato
- BRice
- CGroundnut
- DMore than one option is correct
Correct answer
C. Groundnut
Step-by-step solution
The ratio of the volume of C O 2 evolved to the volume of O 2 consumed in respiration is called the respiratory quotient (RQ). When fats are used in respiration, the RQ is less than 1 . For oxidation of groundnut, fats are oxidized thus value of RQ is less than 1 . In rice and potato the main respiratory substrate is carbohydrates, for which, the RQ value is one.
