Answer:
Aerobic respiration is a set of metabolic reactions that take place in the presence of oxygen, occurring in a cell to convert chemical energy into ATPs. Anaerobic respiration is a process of cellularrespiration where the high energy electron acceptor is neither oxygen nor pyruvate derivatives.

☞ Difference Between Aerobic and Anaerobic Respiration
-----------------------------------------
The primary difference between aerobic and anaerobic respiration is the presence or absence of oxygen during the processes.
More detailed differences are between the two are as follows :-
✒ Aerobic Respiration
- Oxygen is present when this form of respiration takes place.
- Gases are exchanged in this form of respiration.
- It can be found in the cytoplasm and the mitochondria.
- Glucose breaks down into carbon dioxide and water.
- All higher organisms such as mammals have this type of respiration.
✒ Anaerobic Respiration
- Oxygen is absent when this form of respiration takes place.
- Gases are not exchanged in this form of respiration.
- It can be found only in the cytoplasm.
- Glucose breaks down into ethyl alcohol, carbon dioxide and energy.
- Lower organisms such as bacteria and yeast use this type. In other organisms, it occurs during heavy activities.

✏ What is Aerobic Respiration?
- As already stated, cellular respiration can be of two types: aerobic and anaerobic.
- Aerobic means “with air”.
- Therefore, aerobic respiration is the process of cellular respiration that uses oxygen to produce energy from food.
- This type of respiration is common in most of the plants and animals, including humans, birds and other mammals.
- The process can be simply explained with the help of the following equation :-
Glucose + Oxygen → Carbon dioxide + Water + Energy
-----------------------------------------
✏ What is Anaerobic Respiration?
- Anaerobic means “without air”.
- Therefore, this type of cellular respiration does not use oxygen to produce energy.
- Sometimes there is not enough oxygen around for some organisms to respire, but they still need the energy to survive.
- Due to lack of oxygen, they carry out respiration in the absence of oxygen to produce the energy they require, which is referred to as anaerobic respiration.
- The process can be simply explained with the help of the following equation :-
Glucose → Alcohol + Carbon dioxide + Energy
