Q. The respiratory quotient (RQ) of some of the compounds are 4,1 and 0.7. These compounds are identified respectively as
A) Malic acid, palmitic acid and tripalmitin
B) Oxalic acid, carbohydrate and tripalmitin
C) Tripalmitin, malic acid and carbohydrate
D) Palmitic acid, carbohydrate and oxalic acid
Explanation
Respiratory quotient is the ratio of carbon dioxide output to oxygen used during respiration. RQ = $\frac{volume\ of\ carbon\ dioxide\ formed}{volume\ of\ oxygen\ utilized}$ Substrate RQ Carbohydrate 1 Protein 0.80 Fat (tripalmitin) 0.70 Mixed diet 0.85 Organic acids (oxalic acid) 4.0
