Pyruvic acid is a water-soluble, organic liquid that is produced by breaking down carbohydrates and sugars through the glycolytic pathway (glycolysis). If oxygen is available, pyruvic acid is converted to acetyl coenzyme A that ... WebAnaerobic respiration is therefore less efficient than aerobic respiration except, of course, when oxygen is scarce or not apparent. If there is no oxygen present, glycolysis is still able to happen. Pyruvic acid is still produced, but instead of proceeding to the Krebs cycle, lactic acid is formed making small amounts of ATP.

The process by which cells obtain energy from carbohydrates; atmospheric oxygen combines with glucose to form water and carbon dioxide. WebIf oxygen is present, some species of yeast (e.g., Kluyveromyces lactis or Kluyveromyces lipolytica) will oxidize pyruvate completely to carbon dioxide and water in a process called cellular respiration, hence these species of yeast will produce ethanol only in an anaerobic environment (not cellular respiration).
