Difference between aerobic fermentation and anaerobic fermentation

Main difference

The main difference between aerobic fermentation and anaerobic fermentation is that aerobic fermentation redevelops NAD + in an electron transport chain, while anaerobic fermentation redevelops NAD + in glycolysis.

Aerobic fermentation vs. anaerobic fermentation

Anaerobic fermentation is generally the set of chemical reactions that usually involve the formation of energy through the total dissolution of the food, while anaerobic fermentation is usually the chemical analysis of biological substances in lactic acid and ethanol in the presence of oxygen by various microorganisms. Aerobic fermentation generally occurs within living organisms; on the other hand, anaerobic fermentation occurs outside the body of living organisms.

Aerobic fermentation takes place in the mitochondria and cytoplasm, while anaerobic fermentation occurs in the cytoplasm. Aerobic fermentation takes place in higher plants and animals; on the other hand, anaerobic fermentation generally occurs in parasites, bacteria, and yeasts. Aerobic fermentation generally uses the oxygen molecule in the electron transport chain as the final electron acceptor; conversely, anaerobic fermentation occurs in the absence of oxygen and does not use oxygen.

Aerobic fermentation forms six water particles per glucose molecule in cycles; on the contrary, anaerobic fermentation does not undergo the formation of water molecules. Glucose is completely broken down by aerobic fermentation into oxygen and carbon dioxide; on the other hand, glucose is partially or incompletely oxidized in anaerobic fermentation into lactic acid and ethanol. NAD + reproduce in aerobic fermentation in the electron transport chain, while restoration of NAD + occurs in anaerobic fermentation in partial pyruvate oxidation.

ATP is a product of aerobic fermentation in the reproduction of NAD + ; on the other hand, ATP is not a product of anaerobic fermentation in the reproduction of NAD + . 38 forms of ATP in the aerobic fermentation process in prokaryotes and 36 in eukaryotes; on the contrary, 2 ATP are formed in the anaerobic fermentation process. Neither type of microorganism is intricate in aerobic fermentation; on the other hand, microorganisms play a role in anaerobic fermentation.

An ambient temperature is not required in aerobic respiration, whereas ambient temperature is required to perform anaerobic fermentation. The aerobic fermentation method is the energy production process; on the other hand, anaerobic fermentation is the decomposition method. The stages involved in aerobic fermentation are the Krebs cycle, glycolysis, and the electron transport chain, while glycolysis and partial pyruvate oxidation are involved in anaerobic fermentation.

What is aerobic fermentation?

Aerobic fermentation is defined as the chain of chemical reactions that tend to be complicated in the formation of energy by completely dissolving food in the body. Aerobic fermentation generally uses the oxygen molecule in the electron transport chain as the final electron acceptor. The most specific and scientific term for aerobic fermentation is aerobic respiration.

Aerobic fermentation generally arises within living organisms and takes place in higher plants and animals. It usually appears in the mitochondria and the cytoplasm. Neither type of microorganism is intricate in aerobic fermentation. Neither type of microorganism is intricate in aerobic respiration. The aerobic fermentation method is an energy-producing process.

38 forms of ATP in the aerobic fermentation process in prokaryotes and 36 in eukaryotes. Glucose is completely broken down in aerobic fermentation into oxygen and carbon dioxide. Aerobic fermentation forms six water particles per glucose molecule in cycles. The stages involved in aerobic fermentation are the Krebs cycle, glycolysis, and the electron transport chain.

Stages of aerobic fermentation

  • Glycolysis: generally occurs in the cytoplasm of living organisms and is considered the first step that involves aerobic respiration. Glycolysis breaks down or splits glucose molecules into two pyruvate molecules. Pyruvate molecules undergo oxidative decarboxylation to produce Acetyl-CoA. The products of the glycolysis method are 2 NADH and 2 ATP.
  • Krebs cycle : The Krebs cycle splits Acetyl-CoA into carbon dioxide molecules to reproduce oxaloacetate, which is considered as the starting compound. The products of the Krebs cycle are 6NADH, 2GTP, and 2 FADH 2 . It usually takes place within the matrix of the mitochondria.
  • Electron transport chain: During oxidative phosphorylation, the formation of ATP molecules consumes the decreasing energy of NADH and FADH 2 . The electron transport chain generally occurs in the inner membrane of double-membrane mitochondria.

What is anaerobic fermentation?

Anaerobic fermentation is defined as the chemical analysis of biological substances in lactic acid and ethanol in the presence of oxygen by various microorganisms. Most characteristically, anaerobic fermentation releases heat and bubbling. Anaerobic fermentation is usually the chemical analysis of biological substances in lactic acid and ethanol in the presence of oxygen by various microorganisms.

Anaerobic fermentation occurs outside the body of the living organism, generally occurring in the cytoplasm of parasites, bacteria, and yeasts. The stages of anaerobic fermentation are glycolysis and partial oxidation of pyruvate. The two types of anaerobic fermentation are alcoholic fermentation and lactic acid fermentation. 2 forms of ATP in the anaerobic fermentation process.

Types of anaerobic fermentation

  • Alcoholic fermentation: It occurs mainly in yeasts. Fermentation of alcohol involves removal of carbon dioxide and results in decarboxylation of pyruvate to acetaldehyde, which is then generally transformed into alcohol by expending hydrogen atoms from NADH.
  • Lactic acid fermentation: occurs in prokaryotes. During this process, pyruvate is generally transformed into lactic acid.

Key differences

  1. Aerobic fermentation is a type of reaction that causes energy production by completely breaking down food, while anaerobic fermentation is the chemical process of biological compounds.
  2. Aerobic fermentation occurs in living organisms; on the other hand, anaerobic fermentation occurs outside the body of living organisms.
  3. Aerobic fermentation always occurs in the mitochondria and cytoplasm of cells, while anaerobic fermentation takes place in the cytoplasm of the cell.
  4. Aerobic fermentation is very common in higher plants and animals; on the other hand, anaerobic fermentation is very common in parasites, bacteria and yeasts.
  5. Aerobic fermentation takes oxygen gas from the atmosphere and uses it in the electron transport chain; conversely, anaerobic fermentation takes place without oxygen gas.
  6. Aerobic fermentation produces the six water molecules per one glucose molecule in the Krebs cycles; conversely, anaerobic fermentation does not produce water molecules.
  7. Glucose is used entirely in aerobic fermentation and is converted to oxygen and carbon dioxide; on the other hand, glucose is not completely oxidized in anaerobic fermentation and is converted to lactic acid and ethanol.
  8. In aerobic fermentation, NAD + is reproduced in the electron transport chain, while in anaerobic fermentation, restoration of NAD + occurs in the incomplete oxidation of pyruvate.
  9. In the reproduction of NAD + , ATP is an important product in aerobic fermentation; on the other hand, in the reproduction of NAD + , ATP is not an important product in anaerobic fermentation.
  10. 38 ATP produced in prokaryotes and 36 in eukaryotes in aerobic fermentation; on the contrary, 2 ATP produces in anaerobic fermentation.
  11. No microorganisms participate in aerobic respiration; on the other hand, many types of microorganisms are involved in anaerobic fermentation.
  12. Room temperature is not used in aerobic respiration, while room temperature is used in anaerobic fermentation.
  13. The aerobic fermentation process produces energy; on the other hand, anaerobic fermentation is the process of energy breakdown.
  14. The steps of aerobic fermentation are the Krebs cycle, glycolysis, and the electron transport chain, whereas there are no cycles or stages in anaerobic fermentation.
Final Thought

The above discussion concludes that aerobic fermentation is a chemical reaction that usually involves the formation of energy by totally dissolving the food, while anaerobic fermentation is usually the chemical analysis of biological substances. The aerobic fermentation method is the energy production process; on the other hand, anaerobic fermentation is the decomposition method.
