What is the similarity between fermentation and cellular respiration? How is fermentation different from cellular respiration?

– Relate to the processes of energy metabolism: complex organic substances are broken down, the energy enclosed in them is released and ATP is synthesized.
– Represent multistage enzymatic processes.
– These are redox processes (accompanied by oxidation of PVC, reduction and oxidation of NAD, etc.)
– Until the formation of PVC, the processes of fermentation and cellular respiration proceed identically.

– Different energy output. Based on 1 mol of glucose: 2 mol of ATP as a result of fermentation and 38 mol of ATP as a result of complete breakdown of glucose during cellular respiration.
– The final fermentation products are various organic substances (with the exception of CO2), which contain a significant amount of energy. The products of aerobic breakdown of glucose are H2O and CO2.
– O2 is needed for cellular respiration (aerobic), but not for fermentation.
– In eukaryotes, the final (oxygen) phase of cellular respiration occurs in the mitochondria. Fermentation is carried out in the cytoplasm of cells.
