And it does this in three different steps. So in step one it basically binds the reactants, the ATP molecules and the inorganic orthophosphate molecules. In step two it actually catalyzed their combination to form the product molecule, the ATP. And in step number three, the ATP is actually released into the matrix of the mitochondria. Now, I have to emphasize the following important point. So this Heximer structure, this hexamer structure here can actually carry out each one of these steps.
