Now, what about this oxalo acetate? What is the fate of this oxylo acetate? Well, now we actually have to transform the oxalo acetate into a molecule that can move across the membrane back onto the matrix of the mitochondria so that we can recycle and reuse that oxylo acetate. The problem is, oxyloacetate cannot simply diffuse across the membrane of the mitochondria. And we have to transform that oxyloacetate in a two step process into pyruvate. So let's see how this actually takes place.
