Question 8:
What are the differences between aerobic and anaerobic respiration? Name some organisms that use the anaerobic mode of respiration.
Aerobic respiration | Anaerobic respiration | ||
1. | It occurs in the presence of O2. | 1. | It occurs in the absence of O2. |
2. | It involves the exchange of gases between the organism and the outside environment. | 2. | Exchange of gases is absent. |
3. | It occurs in cytoplasm and mitochondria. | 3. | It occurs only in cytoplasm. |
4. | It always releases CO2 and H2O. | 4. | End products vary. |
5. | It yields 36 ATPs. | 5. | It yields only 2 ATPs. |
Anaerobic respiration occurs in the roots of some waterlogged plants, some parasitic worms, animal muscles, and some micro-organisms such as yeasts.
