Similarities And Differences Between Aerobic And Anaerobic Respiration

Cellular respiration is a process that takes place inside the cells where energy is released by the breakdown of glucose molecules. The process can be conveniently divided into two categories based on the usage of oxygen, namely aerobic and anaerobic respiration.

Aerobic and anaerobic respiration both have few similarities and differences. Let us read about it in this article.


(i) In both aerobic and anaerobic respiration, food is broken down to release energy.
(ii) Both take place inside cells.
(iii) Both produce byproducts.

(iv) Carbon dioxide is produced in both reactions.

(v) Energy is released in both reactions.


The difference between the aerobic and anaerobic respiration is tabulated below.

Aerobic Respiration Anaerobic Respiration
 It is the process of cellular respiration that takes place in the presence of oxygen gas.  It is the process of cellular respiration that takes place in the absence of oxygen gas
It involves the exchange of gases between the organism and the outside environment. Exchange of gases is absent.
It can be found in the cytoplasm and the mitochondria It can be found only in the cytoplasm.
Glucose breaks down into carbon dioxide and water. Glucose breaks down into ethyl alcohol, carbon dioxide, and energy
All higher organisms such as mammals have this type of respiration. Lower organisms such as bacteria and yeast use this type.
