In respiration of substrate of organic acids, the R.Q. shall be
Open in App
Solution
The correct option is D More than one
Respiratory quotient (RQ) is the ratio of the volume of carbon dioxide released to the volume of oxygen taken in respiration in the given period of time at standard temperature and pressure. RQ = CO2 eliminated / O2 consumedValue of RQ varies with the respiratory substrates and their oxidation. Thus, the measurement of RQ gives information about the nature of the substrate being respired by a particular tissue.
Name of the substance Respiratory Quotient Carbohydrates 1 Proteins 0.8 - 0.9 Triolein 0.7 Tripalmitin (Fat) 0.7 Malic acid 1.33 Tartaric acid 1.6 Oxalic acid 4.0
Thus, it is clear from the table above that RQ is more than unity for organic acids.
Thus, the correct answer is option D.

| Name of the substance | Respiratory Quotient |
|---|---|
| Carbohydrates | 1 |
| Proteins | 0.8 - 0.9 |
| Triolein | 0.7 |
| Tripalmitin (Fat) | 0.7 |
| Malic acid | 1.33 |
| Tartaric acid | 1.6 |
| Oxalic acid | 4.0 |
Thus, it is clear from the table above that RQ is more than unity for organic acids.
Thus, the correct answer is option D.
