      Pyruvic acid, the key product of glycolysis can have many metabolic fates. Under aerobic condition it forms (a) lactic acid                       (b)                  (c) acetyl        (d) ethanol +

    Answer:

                    (c) Pyruvate, the product obtained through glycolysis, gets oxidised with the loss of its carboxy group as , to give acetyl Co-A, under aerobic condition. This acetyl Co-A is further oxidised completely to in citric acid cycle. Other options are incorrect as Lactic acid is formed in muscles under anaerobic conditions. Ethanol and  are products of anaerobic respiration in yeast cells. and  are final and complete reaction products released at the end of cellular respiration.
