1. Glucose Glucose-6-phosphate
2. Fructose-6-phosphate Fructose-1,6 bisphosphate
3. 2-phosphoglycerate Phosphoenol pyruvate

Aerobic respiration produces more usable chemical energy than fermentation, because fermentation involves
| 1. | formation of lactic acid |
| 2. | complete oxidation of food |
| 3. | partial oxidation of food |
| 4. | evolution of CO2 and alcohol |
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. | \( \dfrac{\mathrm{ Volume ~ of ~ O_{2} ~evolved }}{\mathrm{Volume~ of ~CO_{2} ~consumed }}\) |
The colour in the brown fat is due is
| 1. | its larger capacity for generating heat |
| 2. | large number of mitochondria present |
| 3. | a high concentration of iron containing cytochrome pigments |
| 4. | presence of chromatophores |
Cell respiration is carried out by
(1) ribosome
(2) mitochondria
(3) chloroplast
(4) Golgi bodies
The process by which ATP is produced in the inner membrane of a mitochondrion. The electron transport system transfers protons from the inner compartment of the outer; as the protons flow back to the inner compartment, the energy of their movement is used to add phosphate to ADP, forming ATP.
| 1. | Chemiosmosis | 2. | Phosphorylation |
| 3. | Glycolysis | 4. | Fermentation |
Assertion : Aerobic animals are not truely aerobic.
Reason : They produce lactic acid anaerobically.
- If both the assertion and the reason are true and the reason is a correct explanation of the assertion
- If both the assertion and reason are true but the reason is not a correct explanation of the assertion
- If the assertion is true but the reason is false
- If both the assertion and reason are false
| Assertion(A): | Carbohydrates are more suitable for the production of energy in the body than proteins and fats. |
| Reason(R): | Carbohydrates can be stored in the tissues as glycogen for use in the production of energy, whenever necessary. |
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A) |
| 2. | Both (A) and (R) are true but (R) is not the correct explanation of (A) |
| 3. | (A) is true but (R) is false. |
| 4. | Both (A) and (R) are false. |
