Decarboxylation reactions do not occur in which of these pathways?a. Conversion of Pyruvic acid to Acetyl CoA b. Krebs cyclec. Lactic acid fermentation d. Glycolysis

During lactic acid fermentation, 3 carbon compound pyruvic acid  gets converted to lactic acid which is also a 3-carbon compound. Therefore, CO2 is not released during this process.During glycolysis, 6 carbon glucose ultimately gets converted to 2 molecules of 3 carbon compound pyruvic acid. Therefore, no carbon dioxide is released during the process.
