And it's a complex because we actually have three different enzymes involved in this process. And this complex is very similar to the complex that we spoke about in our discussion on Pyruvate decorboxylation. So once we form this molecule, this molecule that contains the high energy thioester bond is known as succinct coenzyme a. And what happens next is we essentially cleave this high energy bond that releases a certain amount of energy, and the energy that is released is used to basically drive this reaction here the addition of the orthophosphate onto the GDP to form the GTP. In the process, we release the coenzyme a. Now, by the way, step four releases negative 30.1 kilojoules per mole of energy, while step five releases negative 3.3 kilojoules per mole of energy.
