And now we can move that citrate across the inner and then the outer membrane of the mitochondria. And so this, if we recall, is simply the step number one in the citric acid cycle. Now, before we move on to the next steps of this process, actually moving it across the membrane of the mitochondria and then seeing what happens inside the cytoplasm, let's discuss which conditions actually lead to the synthesis of fatty acid. So what conditions do we have to have in the matrix of the mitochondria to actually promote the process of fatty acid synthesis? So, in the matrix of the mitochondria, by the way, this is our matrix, our cytoplasm, the inner and the outer membrane of the mitochondria. So we know that in the matrix we have the citric acid cycle and electron transport chain basically generating ATP molecules.
