We essentially release the carbon dioxide and we form the NADPH. And it's this NADPH that will be used by fatty acid synthesis. In fact, this is the major pathway that produces the highest number of NADPH molecules that will be used by the fatty acid synthesis process. The remaining Nadphs will be produced via the pentose phosphate pathway. Now, once we form pyruvate, it moves across the membranes of the mitochondria into the matrix. And inside the matrix, we use pyruvate carboxylase to transform the pyruvate into oxalo acetate.
