Q. No.The value of respiratory Quotient actually depends upon
1. The type of respiratory substrate used
2. The place in which respiration is occurring
3. The amount of ventilation
4. Breathing surface
The RQ of a substrate is found to be 0.9 what would be that substrate?
(1) Carbohydrate
(2) Fatty Acid
(3) Lipid
(4) Protein
RQ (Respiratory Quotient) is defined as
| 1. | \(\mathrm{Volume~ of ~CO_{2} ~evolved } = \mathrm{ Volume ~ of ~ O_{2} ~ consumed}\) |
| 2. | \( \dfrac{\mathrm{ Volume ~ of ~ O_{2} ~ consumed}}{\mathrm{Volume~ of ~CO_{2} ~evolved }}\) |
| 3. | \(\dfrac{\mathrm{Volume~ of ~CO_{2} ~evolved }}{\mathrm{ Volume ~ of ~ O_{2} ~ consumed}}\) |
| 4. | \( \dfrac{\mathrm{ Volume ~ of ~ O_{2} ~evolved }}{\mathrm{Volume~ of ~CO_{2} ~consumed }}\) |
When (i) are used in respiration the RQ is (ii). Select the correct option for (i) and (ii) that make the sentence a correct sense.
1. (i) Carbohydrates, (ii) > 1
2. (i) Proteins, (ii) > 1
3. (i) Fats, (ii) < 1
4. (i) Malic acid, (ii) < 1
Respiratory Quotient
1. Some Ratio
2. Some amount of oxygen
3. Some amount of carbon dioxide
4. Cannot be one
For the substrate Glucose, how many Oxygen are used and how many Carbon-dioxide are evolved?
1. 3,3
2. 6,3
3. 3,6
4. 6,6
When proteins are used as respiratory substrates, the respiratory quotient would be about:
1. 1.2
2. 1.0
3. 0.9
4. 0.7
When tripalmitin is used as substrate in respiration, the value of RQ is found to be less than one because
| 1. | It contains less number of carbon atoms than oxygen atoms. |
| 2. | The amount of CO2 evolved is more than the amount of O2 consumed. |
| 3. | The amount of O2 consumed is more than the amount of CO2 evolved. |
| 4. | The ratio of the numbers of carbon and hydrogen atoms in this molecule is not 1 : 2. |
Select the correct statement
| 1. | ATP formation occurs both in chloroplast and mitochondria |
| 2. | RQ of protein is 1.5 |
| 3. | RQ of fatty acid is more than one |
| 4. | Cytochrome a3 has both Fe3+ and Fe2+ |
