Decarboxylation of Pyruvate: Products, Process & Significance

Science >> Science Discoveries > >> Chemistry

Decarboxylation of pyruvate produces acetyl-CoA, carbon dioxide, and NADH.

Here's a breakdown of the process:

* Pyruvate is a three-carbon molecule produced during glycolysis.

* Decarboxylation is the removal of a carbon dioxide molecule from pyruvate.

* Acetyl-CoA is a two-carbon molecule that is a key intermediate in metabolism. It is used in the citric acid cycle to generate ATP.

* NADH is a reduced electron carrier that is used in the electron transport chain to generate ATP.

The decarboxylation of pyruvate is catalyzed by the enzyme pyruvate dehydrogenase complex. This complex is located in the mitochondria of eukaryotic cells and is a major control point in cellular respiration.

Overall reaction:

Pyruvate + CoA + NAD+ → Acetyl-CoA + CO2 + NADH + H+
