Now, remember, decorboxylation reactions like the one shown here are generally exergonic reactions. They release energy, and that free energy that is released in the decarboxylation process is used to power the other reactions that are endergonic in this particular process. So once we form this intermediate, the two electrons are then abstracted. They're used to actually reduce the molecule, as we'll see in just a moment. And that allows us to form this intermediate. And now we can couple this intermediate with coenzyme A to form this acetyl coenzyme A complex.
