Question
What are the differences between aerobic and anaerobic respiration? Name some organisms that use the anaerobic mode of respiration.###Differentiate between Aerobic respiration and Anaerobic respiration.
| Aerobic respiration | Anaerobic respiration | ||
| 1. | O2 is used in this process. | 1. | O2 is not used in this process. |
| 2. | At the end of this process CO2 and H2O are produced. | 2. | At the end of this process in medium of plant origin Ethanol and CO2 are produced and in medium of animal origin only lactic acid is produced and no CO2. |
| 3. | In aerobic respiration complete oxidation of glucose molecules occurs, in which one mole of glucose on oxidation releases much greater energy. | 3. | In anaerobic respiration glucose molecules are incompletely oxidized, so one mole of glucose releases less energy along with the organic by - products. |
| 4. | There are two phases in aerobic respiration, the first phase occurs in the cytoplasm and does not utilize O2. The second phase occurs in the mitochondria and utilizes O2. | 4. | There is only one phase in anaerobic respiration. It occurs in the cytoplasm. It occurs entirely in the absence of O2. |
