which metabolic pathway is taking place in resulting the formation of Co2 in preparation f idlies?
Fermentation is the process by which the batter for idli is prepared. The microorganisms perform aerobic or anaerobic respiration that results in formation of CO2. The raising up appearance of the batter is due to the formation of carbon dioxide. By the process of respiration, microorganism breakdown glucose and as a result car bon dioxide is emitted. In case of anaerobic respiration also carbon dioxide and ethanol is released by pyruvic acid which is produced from incomplete oxidation of glucose.
