WebFatty Acid Synthesis is a biochemical pathway which uses the Citrate Shuttle to produce palmitate, a fatty acid, from other molecules. First, citrate from the mitochondrial matrix is shuttled to the cytosol via the citrate shuttle. This citrate is then converted by ATP citrate lyase into Acetyl CoA. Afterwards, Acetyl-CoA is turned into Malonyl-CoA via the Vitamin … The malate-aspartate shuttle (sometimes simply the malate shuttle) is a biochemical system for translocating electrons produced during glycolysis across the semipermeable inner membrane of the mitochondrion for oxidative phosphorylation in eukaryotes. These electrons enter the electron transport chain of the mitochondria via reduction equivalents to generate ATP. The shuttle syst…
