Aerobic Respiration Vs Fermentation. Respiration is actually a concept much talked about in Biochemistry. It is how living things manage to survive and that is through respiration. Respiration has two kinds. One is aerobic, involving oxygen and the other is anaerobic or without the use of oxygen. In the same manner, there is also another phase called fermentation more or less the same as anaerobic but still somewhat different. In the food processing aspect, fermentation has been closely linked to anaerobic respiration because most cases of fermentation do not include oxygen in the process like how grapes are fermented to make wine. Fermentation is technically defined as the conversion of sugar to ethanol chemically speaking. In simpler terms it is transforming carbohydrates into alcohols. One of the most striking differences though between fermentation and aerobic respiration is the end product. difference between fermentation and anaerobic respiration.

difference between fermentation and anaerobic respiration

While studying respiration, I came across a line in one book that anaerobic respiration is different from fermentation in the fact that the final electron acceptor in the electron transport chain in case of anaerobic respiration is any inorganic molecule other than oxygen wheres in case of fermentation it is an organic molecule. Then again it is written difference between fermentation and anaerobic respiration since anaerobic respiration involves incomplete oxidation of glucose so the amount of energy released is way less than that released in case of aerobic respiration.

In the following article it is mentioned that anaerobic respiration proceeds in a similar manner like aerobic respiration i. If that is indeed the case, then why does anaerobic respiration give off less energy than aerobic respiration when the only difference is in the nature of the final electron acceptor?

The fundamental answer is that the energy released transferring electrons to other elements is less than the energy released transferring electrons to O2. Since not as much energy can be released here, not as many ATP molecules can be produced. The electron transport chain is structured just a little differently reducing the numbers of protons differene per pair of electrons from NADH and so less ATP can be produced.
