The co-factor required for the activity of pyruvate dehydrogenase is:
1. Zinc
2. Magnesium
3. Manganese
4. Copper
If fatty acids were to be respired, they would first be degraded to:
1. Glucose-6 phosphate
2. Pyruvate
3. Acetyl-CoA
4. Alpha ketoglutarate
The primary role of oxygen in cellular respiration is to:
| 1. | yield energy in the form of ATP as it is passed down the respiratory chain. |
| 2. | act as an acceptor for electrons and hydrogen, forming water |
| 3. | combine with carbon, forming CO2. |
| 4. | combine with lactate, forming pyruvate. |
Which one of the following mammalian cells is not capable of metabolising glucose to
carbon-dioxide aerobically?
1. White blood cells
2. Unstriated muscle cells
3. Liver cells
4. Red blood cells
The overall goal of glycolysis, Krebs cycle and the electron transport system is the
formation of:
1. ATP in small stepwise units
2. ATP in one large oxidation reaction
3. Sugars
4. Nucleic acids
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 |
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. |
Aerobic Respiration:
1. More common in higher organisms
2. Leads to complete oxidation of Organic substance in the presence of oxygen and release of Carbon-dioxide
3. Large amount of energy present in substrate and amount of water is also released out
4. All of these
