Upload an image of your answers to these questions at the end of the exam. Outline the synthesis of the ketone body, acetoacetate, which forms in the liver under fasting conditions. It is formed in three steps. Include all substrate and product names and structures, enzyme names, and any necessary cofactors or coenzymes. (6 pts.) For the last step in the synthesis of acetoacetate, draw the arrow pushing mechanism for the reaction and identify which reaction in glycolysis it is parallel to. (Hint: Make sure to start your arrow pushing with the structure that has a specific cofactor bonded with another substrate, which goes through an intermediate to synthesize acetoacetate and a second product that is the cofactor). (3 pts.)
