Question

What is the difference between anaerobic respiration and fermentation?

Answer 1

the respiration which occur in the absence of oxygen is called the anaerobic respiration while the fermentation is the chemical breakdown of a substance by bacteria,yeasts or other microorganisms typically involving effervescence and the giving off of heat.

All living things must have a constant source of energy in order to continue performing even the most basic of life functions. Whether that energy comes straight from the Sun through photosynthesis, or by eating other living plants or animals, the energy must be consumed and then changed into a usable form like Adenosine Triphosphate (ATP). There are many different mechanisms that can convert the original energy source into ATP.


The most efficient way is through aerobic respiration, which requires oxygen. This method will give the most ATP per input energy source. However, if no oxygen is available, the organism must still convert the energy using other means. Processes that happen without oxygen are called anaerobic. Fermentation is a common way for living things to continue making ATP without oxygen.

The short answer is no. Even though they both do not use oxygen and have similar parts to them, there are some differences between fermentation and anaerobic respiration. In fact, anaerobic respiration is actually much more like aerobic respiration than it is like fermentation.

Degradation of organic food for the purpose of releasing energy can occur with or without the participation of oxygen. Hence, respiration can be classified into two types: Aerobic and anaerobic respiration.

Aerobic respiration take place in the presence of oxygen and the respiratory substrate gets completely oxidised to carbon dioxide and water as end products. This is often used as a synonym of respiration.

Anaerobic respiration: It is an energy releasing stepwise incomplete catabolic breakdown of food materials without employing oxygen as an oxidant. Some other compounds are also formed in addition to carbon dioxide. This type of respiration is of rare occurrence but common among microorganisms like yeasts.

Fermentation: It is an anaerobic breakdown of carbohydrate and other organic substances with the help of microorganisms or their enzymes. It is a special type of respiration in which organic compounds serve as both the electron donors and the terminal acceptors. Pasteur defined fermentation as life without air. Pyruvic acid is the raw material for fermentation. It is obtained from glycolysis. The end products are alcohol, lactic acid, formic acid, acetic acid. Fermentation is employed by human beings to obtain alcohol and other chemicals.
