When the Earth formed, it’s condition can best be described as:

Upload your answers to these questions. 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. (5 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. (3 pts.)  Ketone bodies are exported from the liver and utilized as an energy source by the extra-hepatic tissues. The brain, which normally utilizes glucose as its energy source, can, under fasting conditions, partially convert to using ketone bodies over the course of a few days. Show how a molecule of the ketone body, -hydroxybutyrate, produced in the liver and exported via the blood to the brain, is utilized for energy production and what advantage this compound has over acetoacetate in terms of cellular energy production. You may use compound names instead of structures. Enzyme names are not necessary. Include any necessary cofactors for full points. (3 pts.) 

Because the partial pressure of oxygen in the blood is lower than that in active muscle tissue, oxygen will naturally diffuse into muscle cells to help support their activity.
