Detailed explanation-1: -Fermentation is the process of producing ATP in the absence of oxygen, through glycolysis alone.
Detailed explanation-2: -In eukaryotic cells, glycolysis and fermentation reactions occur in the cytoplasm. The remaining pathways, starting with pyruvate oxidation, occur in the mitochondria.
Detailed explanation-3: -Mitochondria play a dominant role in respiration but not fermentation; however, they are essential for cell viability regardless of metabolic growth mode. Fermenting cells produce fewer mitochondria than respiring cells.
Detailed explanation-4: -An electron transport system is not involved in fermentation, and no ATP (Adenosine triphosphate) is created directly by the fermentation process. Fermenters make very little ATP-only two ATP molecules per glucose molecule-during glycolysis.
