Pyruvic acid, the key product of glycolysis, can have many metabolic fates. Under aerobic condition, it forms
1. lactic acid
2. CO2 + H2O
3. acetyl Co-A+ CO2
4. ethanol + CO2
Pyruvate, the product obtained through glycolysis, gets oxidised with the loss Of its carboxy group as CO2, to give acetyl Co-A, and this acetyl Co-A is further oxidised completely to CO2 + H2O in citric acid cycle.
Other options are incorrect as Lactic acid is formed in muscles under anaerobic conditions. Ethanol and CO2 are products of anaerobic respiration in yeast cells.
