Pyruvic acid, the key product of glycolysis can have many metabolic fates. Under aerobic condition it forms
Lactic acid
CO2 + H2O
Acetyl CoA + CO2
Ethanol + CO2
Fate of pyruvate after glycolysis -
Pyruvate enters mitochondria when there is an availability of oxygen, where its oxidation is complete.
It is carried out in two phases.
1. Oxidative decarboxylation
2. Krebs cycle.
During oxidative decarboxylation, pyruvate is converted to acetyl co-A and Carbon dioxide is released. Hence the correct option is c.
