Hint: Respiration is the process of releasing energy by the oxidation of food. Respiration is of two types:
- Respiration which occurs in the presence of oxygen is known as aerobic respiration.
- Respiration which occurs in the absence of oxygen is known as anaerobic respiration.
Complete answer:
Definition of Respiration:
Cellular respiration is a set of metabolic responses along with processes that occur in the cells of organisms to transfer chemical energy from oxygen molecules or nutrients into adenosine triphosphate(ATP), and then release the waste product from the body.
Differences between aerobic and anaerobic respiration
Note: Despite being two different types there is some similarity between aerobic and anaerobic respiration such as food is broken down in the presence of oxygen and the end products are water, carbon dioxide and energy.

Differences between aerobic and anaerobic respiration
| Aerobic Respiration | Anaerobic Respiration |
| Aerobic respiration is a set of metabolic reactions that occurs in the presence of oxygen, occurring in a cell to convert chemical energy into ATPs. | Anaerobic respiration is a process of cellular respiration in which the high energy electron acceptor is neither oxygen nor pyruvate derivatives. |
| Aerobic respiration found in the presence of oxygen. | Anaerobic respiration occurs in a condition where there is a low oxygen. |
| The end products of aerobic respiration are carbon dioxide, water, as well as energy. | The end products of anaerobic respiration are acids, alcohols, gases, as well as energy. |
| Aerobic respiration is comparatively longer. | Anaerobic respiration is shorter. |
| Aerobic respiration takes place in most of the higher organisms like plants as well as animals. | Anaerobic respiration takes place in primitive prokaryotes. Anaerobic respiration is also found in the muscle cells in humans during extremes. |
Note: Despite being two different types there is some similarity between aerobic and anaerobic respiration such as food is broken down in the presence of oxygen and the end products are water, carbon dioxide and energy.
