5 When your body metabolizes fat for energy, it gets 9 Cal./g, as opposed to only 4 Cal./g from protein (muscle). Knowing this,explain why your body uses adipose tissue rather than muscle tissue as the "default" energy store.

3. What is the difference between calorie, ATP and GTP? How is GTP converted to ATP? Also explain the synthesis of ATP. Proper explanation and diagram
This is homework
7. In the ketone body pathway, both acetoacetate and B-hydroxy butyrate are produced and become additional fuel molecules for the organism. a. Define where these molecules are produced (both tissue type and location in the cell) and what tissue they "feed". b. Of these two molecules, which one is considered slightly better in delivering more energy to the target tissue? Why? c. How does acetone, another ketone body, participate in delivering fuel to target tissue? d. If acetoacetate decarboxylase enzyme was mutated and became inactive (zero enzyme activity), how would this affect the ketone pathway during these conditions: į. immediately after a meal, ii. under starvation conditions, iii. during unchecked (not being treated for) type-1 diabetes.

3. Choice is good . Glycogen is not as reduced as fatty acids are and consequently not as energy rich. Why do animals store any energy as glycogen? Why not convert all excess fuel into fatty acids?
Products of lipolysis (intracellular TAG hydrolysis), fatty acids and glycerol are released from adipose tissue when energy demands increase during fasting Select INCORRECT statements (Select ALL)? OA. Glucagon inhibits lipolysis in adipose tissues 8. Fatty acids are used for synthesis of ketone bodies in the liver OC. Fatty acids are used as energy substrate in muscle sparing glucose for brain and glucose obligatory cells D. Ketones are used as alternative fuels in muscle sparing glucose for brain use E. Ketone synthesis increases when there is sufficient oxaloacetate for the TCA cycle to run F. Glycerol is mainly uptaken into muscle and used as an energy source during fasting
Fill in the blanks. Write your answer as a range of calories. For example, if the answer is 400-700, write the answer exactly as 400-700. Don't add any spaces or extra characters. If your estimated energy requirements are 2000 kcal per day, you should be getting 900-1300 kcal/day from carbohydrates, 200-700 kcal/day from fat. kcal/day from protein, and 100-120
