State if the following statement is true or false. Correct the statement if it is false.
The oxidation of food to release energy and water is called breathing.
State if the following statement is true or false. Correct the statement if it is false.
The microscopic air sacs present in the lungs are called bronchi.
Given below are chemical reactions (1 to 5) involving glucose and five other chemical products (A-E).
Which reactions (1-5) in the above correspond to the following (write the corresponding number of reaction next to them).
(i) Aerobic respiration
(ii) Change taking place in the liver
(iii) Anaerobic respiration in yeast
(iv) Change taking place in a plant
storage organ, e.g., potato
(v) Anaerobic respiration in animals
Distinguish between:
Aerobic respiration and anaerobic respiration.
Give the overall chemical equation that represents anaerobic respiration in plants.
Name the following:
The products formed as a result of anaerobic respiration.
What is the common step in the aerobic and anaerobic pathways?
Identify the reasons due to which less energy is produced during anaerobic respiration than in aerobic respiration.
- Incomplete breakdown of the respiratory substrate.
- NADH2 does not produce ATP, as electron transport is absent.
- Glycolysis does not occur during anaerobic respiration.
Study the following statements with respect to Krebs cycle and select the correct option.
- As per need, acetyl CoA or some other intermediates like a-ketoglutarate, oxaloacetate of Krebs cycle are used as precursors for synthesis of fatty acids, glutamic acid and aspartic acid respectively.
- Various reactions of Krebs cycle involve step-wise oxidation of acetyl part of acetyl CoA leading to release of energy and C02.
Match the Column I (ETS Complex) to Column II (Characteristic) and select the correct option.
| Column I | Column II | ||
| i. | Complex I | a. | Succinate dehydrogenase |
| ii. | Complex II | b. | Cytochrome oxidase |
| iii. | Complex III | c. | NADH dehydrogenase |
| iv. | Complex IV | d. | Cytochrom bc1 complex |
The CORRECT combination of statements with respect to oxidative phosphorylation is
- Cytochrome 'C' oxidase complex contains cytochromes a and a3, and two cobalt centers.
- Cytochrome 'C' is a small mobile electron carrier protein.
- Oxidation of NADH2 and FADH2 give rise to 3 molecules of ATP.
- Light energy is not utilized for the production of proton gradient required for phosphorylation.
______ acts as carrier for transferring the elecu·ons in electron transport system.
During which of the following reactions substrate-level phosphorylation occurs?
