Title: Briefly explain the differences between cellular respiration and fermentation. H Post by: barry on Feb 9, 2012 Briefly explain the differences between cellular respiration and fermentation. How do these processes differ in terms of energy output for the cell?
Title: Re: Briefly explain the differences between cellular respiration and fermentation. H Post by: bio_man on Feb 9, 2012 Cellular respiration begins in the cytoplasm of a cell (glycolysis) and continues within the mitochondria (the transition reaction, citric acid cycle, and electron transport system). A total of 36 ATP molecules is produced by this metabolic pathway. Fermentation involves the breakdown of glucose in the cytoplasm (glycolysis), producing lactic acid in eukaryotes. There are only 2 ATP molecules produced in this pathway, both of which are generated in glycolysis. Cellular respiration requires oxygen; fermentation does not.
