What is the difference between respiration and fermentation

It uses glucose, produces ATP and another substance as a product. In the process of fermentation, there is less energy being produced than respiration. It also gets its energy directly from the glucose. In order for a yogurt to undergo fermentation, lactate bacteria is being added to milk. The lactate bacteria will then ferment it. Thus, the final product is a yogurt with a sour taste. In other products such as beer, the process can be overhauled by sealing the alcoholic beverage. In this manner, at the latter part of fermentation, it will produce beer as its final product.

It is also the same with root beer. Due to the process of respiration, all of the living things in this planet are able to breathe. We humans breathe because of the exchange of oxygen and carbon dioxide inside our lungs. For fermentation, food and other beverages will not exist without this important process. In our body, fermentation acts via pepsin and rennin which acts to ferment and soften the food we eat to aid in the digestion and absorption of nutrients.

Respiration or anabolic respiration involves the use of oxygen while fermentation involves the use of enzymes such as glucose.

Fermentation and respiration are two types of cellular processes, involved in the breaking down of glucose in the cell. Both fermentation and respiration are catabolic processes, generating energy in the form of ATP.

Fermentation is the chemical breakdown of organic substrates like glucose by microorganisms like bacteria and yeast, typically giving off effervescence and heat.

It occurs in microorganisms like some bacteria, yeast, and parasitic worms. The net yield of fermentation is only 2 ATPs. The process of fermentation occurs in two steps: glycolysis and partial oxidization of pyruvate. There are two types of fermentation known as ethanol fermentation and lactic acid fermentation.

Ethanol fermentation occurs in yeast in the absence of oxygen. Hence, they are called facultative anaerobes. Lactic acid fermentation occurs in bacteria. In the absence of oxygen, animals also produce lactic acid mainly in their muscles. Lactic acid is toxic to tissues. Glycolysis is same for both fermentations. During glycolysis, glucose is broken down into two pyruvate molecules, generating 2 ATPs as the net gain.

Other than that, two molecules of NADH are formed by obtaining electrons from glyceraldehydephosphate. During ethanol fermentation, pyruvate is decarboxylated into acetaldehyde by removing carbon dioxide. Acetaldehyde is converted into ethanol by using the hydrogen atoms of the NADH. The effervescence occurs due to the releasing of carbon dioxide gas into the medium by the cells in the medium. During lactic acid fermentation, pyruvate is converted into lactic acid, which is then oxidized into lactate.

The overall chemical reaction for ethanol fermentation and lactic acid fermentation are given below. Lactic Acid Fermentation:. Figure 1: Ethanol and lactic acid fermentation. Respiration is the set of chemical reactions involved in the production of energy by completely oxidizing food.

It releases carbon dioxide and water as by-products. Cellular respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. Glycolysis is an anaerobic process. The other two stages are aerobic processes.

The reactions of cellular respiration can be grouped into three stages: glycolysis, the Krebs Cycle, and electron transport. Cellular respiration uses energy in glucose to make ATP. In glycolysis, glucose is split into two molecules of pyruvate. Three types of respiration include internal, external, and cellular respiration. It involves inhalation and exhalation of gases. Internal respiration involves gas exchange between the blood and body cells.

Cellular respiration can occur both aerobically using oxygen , or anaerobically without oxygen. During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell.

Carbon dioxide and water are created as byproducts. Without oxygen, organisms can split glucose into just two molecules of pyruvate. This releases only enough energy to make two ATP molecules.

With oxygen, organisms can break down glucose all the way to carbon dioxide. Thus, aerobic respiration releases much more energy than anaerobic respiration. Oxygen is the final electron acceptor of the electron transport chain in the final step of cellular respiration. Oxygen combines with electrons and hydrogen ions to produce water. As it turns out, oxygen is the essential ingredient for making energy in a process called cellular respiration. All body cells engage in cellular respiration.

They use oxygen and glucose, a sugar found in the foods we eat and convert them to ATP adenosine triphosphate , or cellular energy, and carbon dioxide. Some examples of anaerobic respiration include alcohol fermentation, lactic acid fermentation and in decomposition of organic matter. Though it does not produce as much energy as aerobic respiration, it gets the job done. Anaerobic respiration is economically important — many of our foods are produced by microorganisms respiring anaerobically.

Yeast is used to make alcoholic drinks.
