   D+E=G+F G=+9kcal/mol
   F+H=I+J G=-4kcal/mol
   
   a. A+B will be converted to C+D
   b. G+F will be converted to D+E
   c. D+E will be converted to F+G
   d. F+H will be converted to I+J

2. A woman had a heart attack caused by thrombus. the cells immediately downstream from the thrombus were deprived of oxygen and , as a result, increased:
   a. glycolysis
   b. flux through the TCA cycle
   c. production of mitochondrial ATP
   d. flux through the electron transport system

3. Which is glucoranate out of the below?

4. 

5. You are following the blood glucose concentrations of a normal subject who has ingested a high carbohydrate meal. which of the following statements is INCORRECT?
   a. at 40 minutes, blood glucose is 130 mg per dl. the source of glucose is the diet
   b. at 2 hours, blood glucose is 140 mg per dl. the source of glucose is the diet
   c. at 12 hours, blood glucose is 85 mg per dl. the source of glucose is both glycogenolysis and gluconeogenesis
   d. at 24 hours, blood glucose is 70 mg per dl. the source of glucose is mostly gluconeogenesis
   e. at 3 days, blood glucose is 65 mg per dl. the souce of glucose i

   a. a hemoglobin A1c that is slightly lower than normal
   b. a slightly lower than normal release of insulin in reps once to increases in glucose
   c. muscle cells that are super sensitive to insulin
   d. adipose cells that are super sensitive to insulin
   e. more glucose entering muscle cells than normal following a high carbohydrate meal
7. glucagon specifically does all of the following except:
   a. stimulates the release of glucose from the liver via glycycogenolysis
   b. activates the enzymes of gluconeogenesis to form glucose in the liver
   c. mobilizes fatty acids from triacylglycerols in adipose tissue
   d. activates fructose-2,6 bisphosphate in liver.
   e. influences gluconeogenesis in muscles to make glucose for energy
