Q. No.If fatty acids were to enter the respiratory pathway, they must be converted to a molecule with:
| 1. | Two carbons | 2. | Three carbons |
| 3. | Five carbons | 4. | Six carbons |
Subtopic: Aerobic Respiration | Respiratory Quotient | ETS:2 | ETS:1 | ETS |
62%
Level 2: 60%+
Hints
The correct descending order of the RQ value, when carbohydrates, proteins and fats are used as respiratory substrate would be:
1. Protein ˃ Fats ˃ Carbohydrates
2. Protein ˃ Carbohydrates ˃ Fats
3. Carbohydrates ˃ Protein ˃ Fats
4. Fats ˃ Carbohydrates ˃ Protein
Subtopic: Respiratory Quotient |
84%
Level 1: 80%+
Hints
The following equation shows the complete oxidation of tripalmitin [a fatty acid] during cellular respiration. Calculate the RQ:
\(2(C_{51}H_{98}O_6)+145O_2\longrightarrow \\102CO_2+98H_2O+\text{energy}\)
\(2(C_{51}H_{98}O_6)+145O_2\longrightarrow \\102CO_2+98H_2O+\text{energy}\)
| 1. | 0.7 | 2. | 0.9 |
| 3. | 1.0 | 4. | 4.0 |
Subtopic: Respiratory Quotient |
90%
Level 1: 80%+
Hints
When proteins are respiratory substrates, the respiratory quotient is about:
| 1. | 0.7 | 2. | 0.9 |
| 3. | 1.0 | 4. | 4.0 |
Subtopic: Respiratory Quotient |
88%
Level 1: 80%+
