Hi, For this answer, i am assuming you have some high school Biology knowledge (general understanding of glycolysis, kreb cycle, pyruvate oxidation etc..) Anaerobic respriation and fermentation differ in the chemical pathways. Fermentation occurs when the pyruvate (or some derivative of it) that is produced after glycolysis is reduced by NADH to usually form an organic compound (lactic acid in lactic acid fermentation and ethanol in alcoholic fermentation). It is important to note that fermentation does not have to occur in anaerobic evironments, for example yeast prefers fermentation even in the presence of oxygen (as long as sugars are available). Therefore, the defining characteristic of fermentation is that the electrons from the coenzymes (NADH from the glycolosis) are transfered back to part of the original substrate (pyruvate). Note that the electrons are donated to something which came from within the cell (pyruvate). On the other hand, anaerobic respiration is actually very similar to aerobic respiration. In anaerobic respiration, you would go through glycolysis, pyruvate oxidation, kreb cycle and then electron transfer chain just as you would in aerobic respiration with the difference that that the terminal electron acceptor is NOT oxgyen (nitrate, nitrite etc..). The defining characteristic here is that the terminal electron acceptor is anything by oxygen but otherwise, it is very similar to aerobic respiration. Note that the electrons are donated to something which came from outside the cell (nitrate, nitrite etc..). Therefore, fermentation goes something like glycolysis -> donating electron back to pyruvate or a derivative of pyruvate (electron acceptor from internal source); while anaerobic respiration goes something like glycolysis -> pyruvate oxidation -> kreb cycle -> electron transfer chain with terminal electron acceptor being anything but oxygen (electron acceptor from external source). Hope this made sense

aerobic respiration uses oxygen and fermentation does not. aerobic respiration creates more energy (ATP) than fermentation. aerobic respiration (36 ATP), fermentation (2 ATP).

hope this helped :)

Aerobic respiration is more efficient than anaerobic respiration.

One glucose molecule has enough energy stored in it to produce 38 molecules of ATP,and fats contain roughly two times more energy than glucose.Glucose is the most common respitory substrate.

Glucose + Oxygen + ADP+Pi --> Carbon Dioxide + Water + ATP

Anaerobic respiration is the respiration of some cells in the absence of oxygen.

This is much less efficient than aerobic respiration as the second stage cannot take place i.e. the pyruvic acid produced during during glycolysis cannot be converted to carbon dioxide and water because there is no oxygen to combine with with the hydrogen to make water.

Consequently only two ATP molecules are produced and the end products of the process are still high in energy.In plants the high-energy end product is ethanol(alcohol) and in animals the high-energy end product is lactic acid.

Plants also produce carbon dioxide during anaerobic respiration. Here is a simpler answer:

Anaerobic respiration is when an organism lives without oxygen.

Aerobic respiration is when an organism needsoxygen to live.

The main difference between aerobic and anaerobic is that one has exposure to oxygen while the other does not. In respiration, aerobic is the desired choice. In fermentation, some fermenting sources prefer to have no oxygen in their environment, while other sources would prefer the contrary.

Aerobic respiration is respiration using air. Anaerobic respiration is respiration not using air. Only certain organisms can do respiration without air.

What does 'anaerobic respiration is far less efficient than aerobic respiration' mean?

There are two types of cellular respiration: aerobic and anaerobic. Aerobic respiration occurs when there is oxygen present. In total, 36 ATP are produced by the end of aerobic respiration. Anaerobic respiration occurs when there is no oxygen present. In total, just 4 ATP are produced by the end of anaerobic respiration. Thus, aerobic respiration is more efficient in comparison to anaerobic respiration as it yields more ATP
