Schematic comparison between glucose (orange) and xylose (blue) metabolisms in engineered S. cerevisiae. Colored distinction of arrows indicates which sugar induce each metabolic pathway to be predominant. Xylose-derived weaker glycolysis metabolic activity and dysregulation of glucose repressions on cytosolic acetyl-coA synthetic pathway and mitochondrial development (green) allowed S. cerevisiae to more efficiently produce derivatives of pyruvate and cytosolic acetyl-CoA
