What are the differences between aerobic and anaerobic respiration? Name some organisms that use the anaerobic mode of respiration.
What is the main difference between aerobic respiration and anaerobic respiration? Give one example of each.
उत्तर
| Aerobic respiration | Anaerobic respiration |
| It occurs in the presence of O2. | It occurs in the absence of O2. |
| It involves the exchange of gases between the organism and the outside environment. | Exchange of gases is absent. |
| It occurs in cytoplasm and mitochondria. | It occurs only in cytoplasm. |
| It always releases CO2 and H2O. | End products vary. |
| More energy is released. | Less energy is released. |
| For example, plants and animals (eukaryotes). | For example, yeast, bacteria. |
Some organisms that use the anaerobic mode of respiration are - yeast, bacteria, etc.

When a person breathes in the air, the air enters into his body through an organ A having two holes B in it. The air then passes through the pharynx and larynx and enters into tube C. The tube C divides into two smaller tubes D at its lower end. The two smaller tubes are attached to two respiratory organs E. Each smaller tube divides inside the organs E to form a large number of still smaller tubes called F. The smallest tubes F have air-sacs G at their ends in which gaseous exchange takes place in the body of the person. What are A, B, C, D, E, F, and G?
