Respiration is of two types-
Aerobic Respiration-means a cellular respiration process in which glucose is broken down in the presence of oxygen to produce energy. This energy is used in various body functions. It usually occurs in plants, animals, humans and other mammals also. It has mainly three stages-
Anaerobic Respiration-As the name says this type of respiration takes place without oxygen as oxygen is not required to break the glucose into energy. It usually occurs in unicellular organisms like bacteria fungi, protozoa etc.
Let us now understand the differences in the table given below-
Aerobic Respiration |
Anaerobic Respiration |
Happens only in presence of oxygen. |
Oxygen is not required. |
Always produce carbon dioxide and water along with ATP molecules. |
It may vary carbon dioxide ethanol lactic acid along with ATP molecules. |
Occurs in a multicellular organism. |
Occurs in Unicellular organisms. |
Takes place in the cytoplasm as well as mitochondria. |
Takes place in the cytoplasm. |
It has 3 steps- Glycolysis Kreb’s cycle Electron Transport chain |
It has 2 steps- Glycolysis Fermentation |
Exchange of gases happens. |
The exchange of gases does not take place. |
