Anaerobic respiration requires oxygen.

|
|
Anaerobic respiration does NOT require oxygen.

|
|
Anaerobic respiration occurs only at the cellular level.
|
|
|
Anaerobic respiration only occurs outside of the cell.

Detailed explanation-1: -Aerobic Respiration-Takes place in the presence of oxygen. Anaerobic Respiration –Takes place in the absence of oxygen.
Detailed explanation-2: -Anaerobic respiration is a normal part of cellular respiration. Glycolysis, which is the first step in all types of cellular respiration is anaerobic and does not require oxygen. If oxygen is present, the pathway will continue on to the Krebs cycle and oxidative phosphorylation.
Detailed explanation-3: -Aerobic respiration requires the presence of oxygen to produce energy from food. It is the most common type of respiration seen in plants and animals.
Detailed explanation-4: -The breakdown of glucose occurs in the cells of an organism (cellular respiration). If the food is broken down with the use of oxygen, it is called aerobic respiration. If the breakdown occurs without the use of oxygen, the respiration is called anaerobic respiration.
Detailed explanation-5: -Glycolysis is a common step for both aerobic and anaerobic respiration. It takes place in the cytoplasm and is independant of the presence or absence of oxygen.
