When proteins and fats are used in respiration, the RQ value is less than one as they
Oxidized under anaerobic conditions
Contain less oxygen
Require relatively lesser amount of O2 for oxidation
Are favoured substrates for cellular respiration
Carbohydrates are favoured substrates for respiration
Assertion (A): RQ value of fats and proteins is less than one
Reason (R): Fats and proteins consume more oxygen than carbohydrates do, during their oxidation
