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 that 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? difference between fermentation and respiration
Figure 1: Ethanol and lactic acid fermentation What is Respiration 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.
Respiration is the most abundant and most efficient process among the processes of energy production. It occurs in higher plants and animals who are using complex cellular processes with high energy consumptions. During respiration, 36 ATPs are produced.
The whole process occurs in the cytoplasm and mitochondria. Respiration occurs through difference between fermentation and respiration steps: glycolysis, citric acid cycle and electron transport chain. Glycolysis occurs in the cytoplasm of the cell in the same way it occurs during fermentation. The two pyruvate molecules produced in the glycolysis is transferred into the diffsrence matrix. They release two carbon dioxide molecules, one from each and become acetyl-CoA during oxidative decarboxylation. This acetyl-CoA enters into the citric acid cycle, which is also known as Krebs cycle. During the oxidative phosphorylation, electrons in NADH and FADH2 are transferred through a series of electron carriers called electron transport chain.
The net yield of ATPs is thirty six in respiration.
The overall chemical reaction is shown below. Respiration: Respiration is the set of chemical reactions involved in the production of energy by completely oxidizing food. Oxygen Fermentation: Oxygen is not required for fermentation. Respiration: Oxygen is required for respiration. Water Fermentation: No water is produced during fermentation.
Respiration: Water is produced as a by-product respiratino respiration.
Main Difference – Fermentation vs Respiration
Occurrence Fermentation: Fermentation occurs in the cytoplasm. Respiration: Respiration occurs in cytoplasm and mitochondria. Respiration: Respiration generates 36 ATPs by the breaking down of a single glucose molecule.]
