How Is Acetyl CoA Completely Oxidized?

How Is Acetyl CoA Completely Oxidized? Acetyl-CoA is generated either by oxidative decarboxylation of pyruvate from glycolysis, which occurs in mitochondrial matrix, by oxidation of long-chain fatty acids, or by oxidative degradation of certain amino acids. Acetyl-CoA then enters in the TCA cycle where it is oxidized for energy production. Does acetyl CoA get oxidized?
