Anaerobic Respiration vs. Fermentation

The main difference between anaerobic respiration and fermentation is that anaerobic respiration undergoes electron transport chain and citric acid cycle, whereas fermentation does not undergo electron transport chain and citric acid cycle.

Key Differences

Glycolysis follows the electron transport chain and citric acid cycle in anaerobic respiration; conversely, glycolysis does not follow the electron transport chain and citric acid cycle in fermentation.

Anaerobic Respiration and Fermentation Definitions

Fermentation

Any of a group of chemical reactions induced by microorganisms or enzymes that split complex organic compounds into relatively simple substances, especially the anaerobic conversion of sugar to carbon dioxide and alcohol by yeast.

Fermentation

Unrest; agitation.

Fermentation

(biochemistry) Any of many anaerobic biochemical reactions in which an enzyme (or several enzymes produced by a microorganism) catalyses the conversion of one substance into another; especially the conversion (using yeast) of sugars to alcohol or acetic acid with the evolution of carbon dioxide

Fermentation

A state of agitation or excitement; a ferment.

Fermentation

The process of undergoing an effervescent change, as by the action of yeast;

What is Anaerobic Respiration?

Anaerobic respiration refers to a category of cellular respiration that happens in the absence of oxygen and a stepwise incomplete catabolic breakdown of food materials. Anaerobic respiration occurs in many environments such as in marine sediments and freshwater, soil, subsurface aquifers, biofilms, and deep subsurface environments. Even present in environments where oxygen is present and also have microorganisms that lack oxygen because of the slow diffusion of oxygen gas. The way of the procedure is the same as aerobic respiration. This process begins with glycolysis as also in the fermentation process, but fermentation stops from it as anaerobic respiration does not. Anaerobic respiration continues the electron transport chain as well as citric acid cycle after the production of acetyl coenzyme A. As in aerobic respiration, the molecular oxygen is not the final electron acceptor in anaerobic respiration. Different types of organisms use different categories of final electron acceptor which can be nitrate ions, sulfate ions, or carbon dioxide. With the help of an example, this can be explained as methanogenic bacteria is a type of organisms that uses carbon dioxide as its final electron acceptor in anaerobic respiration. This bacterium produces methane gas as a byproduct. Anaerobic respiration plays an important role in ecological importance. Biogeochemical cycling depends on anaerobic respiration which significantly impacts the global warming and carbon cycle. Some specific types of anaerobic respiration are also important in bioremediation which converts toxic chemicals into less-harmful molecules to clean up the contaminated environment by using microorganisms.

Examples

Aerobic prokaryotes, and Eukaryotes.

What is Fermentation?

Fermentation refers to any chemical reactions to convert sugars into carbon dioxide and ethanol and breakdown of carbohydrates and other organic substances induced by microorganisms. Since fermentation doesn’t use the citric acid cycle or electron transport chain, so fermentation isn’t considered a type of respiration. The procedure of fermentation continues in which first sugar undergoes glycolysis. The hexose sugar glucose is gone down into two pyruvates during glycolysis. Glycolysis uses two ATP molecules while producing a total four molecules of ATP from the energy released from glycolysis. The pyruvate is oxidized into lactic acid, ethanol, formic acid, acetic acid. The raw material of fermentation is pyruvic acid. Some bacterial species and yeast perform fermentation.

Types

  • Ethanol Fermentation: It is used to produce bread, beer, and wine. Some other organisms undergo ethanol fermentation where the results are neither lactic acid nor pyruvate. In this case, these organisms make ethyl alcohol.
  • Lactic Acid Fermentation: It is used to produce lactic acid from lactose in yogurt production. Lactic acid fermentation happens in animal muscles and tissues when there is more required in energy in tissues. Distance runners are aware of lactic acid which build up in the muscles and cause cramping.

Examples

Beer, Wine, Cheese, Yogurt, Certain sour foods containing lactic acid, etc.
