Questions
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.
Solution
| 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.

There is a pair of bean-shaped organs P in the human body towards the back, just above the waist. A waste product Q formed by the decomposition of unused proteins in the liver is brought into organ P through blood by an artery R. The numerous tiny filters S present in organ P clean the dirty blood by removing the waste product Q. The clean blood goes into circulation through a vein T. The waste substance Q, other waste salts, and excess water form a yellowish liquid U which goes from organ P into a bag-like structure V through two tubes W. This liquid is then thrown out of the body through a tube X.
