Describe the sequence of conversion of pyruvic acid in the process of biological oxidation

Describe the sequence of conversion of pyruvic acid in the process of biological oxidation. What reactions produce carbon dioxide? What organoid cells do these processes go to?

Pyruvic acid is cleaved to acetyl coenzyme A by subsequent oxidative decarboxylation of pyruvic acid; fatty acids are converted by acetal-coenzyme A by p-oxidation, etc. These specific pathways correspond to stage II of catabolism and are considered in the corresponding sections of metabolism (carbohydrate metabolism, fat metabolism, etc.).
As a result of oxidation by oxygen, glucose breaks down into carbon dioxide and water. These reactions occur mainly in the mitochondria.
