And notice this molecule doesn't actually show up because it acts as an intermediate. When we sum up these molecules, these two molecules actually cancel out. And so that intermediate will not appear in this overall net reaction. So this is basically a two step process in which the cells basically activate the fatty acid molecule and prepared for transfer into the matrix of the mitochondria. Now, once we form that acyl coenzyme A, the next step is to basically transfer or the next step is to transport it into the matrix of the mitochondria. Now, before the acyl coenzyme A molecule can actually be transferred, it has to be converted into another molecule.
