According to NCERT textbook, what is the number of ATP molecules that can be regarded as a net gain during aerobic respiration of one molecule of glucose?
1. 2 | 2. 30 |
3. 36 | 4. 38 |
What is the number of ATP molecules produced when pyruvate is converted to lactate by fermentation?
1. 0 | 2. 2 |
3. 4 | 4. 38 |
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 |
The respiratory pathway is best described as:
1. | Catabolic | 2. | Anabolic |
3. | Amphibolic | 4. | Amphipathic |
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
Phosphorylation of glucose during glycolysis is catalysed by
1. Phosphoglucomutase | 2. Phosphoglucoisomerase |
3. Hexokinase | 4. Phosphorylase |
Pyruvic acid, the key product of glycolysis can have many metabolic fates. Under aerobic condition, it forms
1. | Lactic acid | 2. | CO2 + H2O |
3. | Acetyl CoA + CO2 | 4. | Ethanol + CO2 |
Which of the following exhibits the highest rate of respiration?
1. Growing shoot apex | 2. Germinating seed |
3. Root tip | 4. Leaf bud |
What is the end product of glycolysis?
1. NADH | 2. ATP |
3. G3P | 4. Pyruvate |
The outputs of the Krebs cycle do not include:
1. NADP | 2. |
3. ATP | 4. |
