This entire process, it releases the carbon dioxide molecule and attaches a two carbon component of the pyruvate onto a special molecule, a carrier molecule known as coenzyme A, or COA. And we formed the CETO coenzyme A complex, and this activates the two carbon fuel source of that pyruvate so that now we can actually transfer this component into the citric acid cycle. In the process. We also actually abstract two electrons from the pyruvate. And those two electrons are picked up by the nicotine and nicotine amide adenine dinucleotide molecule to form NADH. And so this is the net process that we call pyruvate carboxylation.
