**Question 19: Metabolic Pathways and Enzyme Reactions****Which of the following statements is true for the shown reactions?****Reaction Diagram Description:**- **W to X Transformation:** - The molecule labeled **W** (chemical structure: C-S-CoA, CH2, H3C-C-OH, CH2, COO-) undergoes a transformation resulting in the molecule labeled **X** (chemical structure: COO-, CH2, C=O, CH3). - This transformation involves an intermediate which is Acetyl-CoA.- **X to Y Transformation:** - The molecule **X** (chemical structure: COO-, CH2, C=O, CH3) is further transformed into the molecule labeled **Y** (chemical structure: COO-, CH2, CHOH, CH3). - This transformation involves the addition of a Hydrogen (2H).**Option A:**- **Deficiency of oxaloacetate stimulates the formation of X and Y****Option B:**- **Insulin signaling stimulates the formation of X and Y****Option C:**- **Both A and B****Option D:**- **Neither A nor B****Answer:**This question tests the understanding of the metabolic conversions and regulatory factors influencing the formation of intermediary compounds X and Y. The student is expected to apply knowledge of biochemical pathways and their regulation.
