UNE BioChem Unit 4 Final EXAM With Solutions The processes of beta oxidation and fatty acid synthesis are regulated in such a manner that these processes are not active at the same time. Which of the following enzymes required for beta oxidation is paired with the correct inhibitor? - Answer -Carnitine acyl-transferase-1/Malonyl CoA citrate synthase, acetyl CoA A healthy female is 20 weeks pregnant, she is consuming an average diet that contains 60% carbohydrate, 20% fat and 20% protein. This individual would be in ___________________ nitrogen balance. - Answer -Postitive If you were being chased by a bear in the woods, all the following pathways would contribute to increasing circulation of free fatty acids and glucose EXCEPT: - Answer -Lipolysis A 5-year old girl displayed increased appetite, increased urinary frequency, and thirst. Her physician suspected new onset diabetes mellitus and confirmed that she had elevated urine glucose and ketones. Serum levels of free fatty acids were not measured in this patient, however; based on the data presented above you would expect them to be (when compared to a healthy individual): - Answer -a. They rise because of unrestrained lipolysis*** A 5-year old girl displayed increased appetite, urinary frequency, and thirst. Her physician suspected new onset diabetes mellitus and confirmed that she had elevated urine glucose and ketones. If this individual were to have an episode of diabetic ketoacidosis, you would expect her blood gas analysis to show which of the following characteristics consistent with respiratory compensation during this event? - Answer -...Low bicarbonate, low pH, low PCO2 (partial pressure of carbon dioxide)*** A 5-year old girl displayed increased appetite, urinary frequency, and thirst. Her physician suspected new onset diabetes mellitus and confirmed that she had elevated urine glucose and ketones. Blood glucose levels were 250mg/dL (normal range 90-120 mg/dL). In this girl, the increase in blood glucose is primarily due to which of the following? a) Increase heptic gluconeogenesis b) Increase lipolysis c) Decrease in glucose uptake by GLUT 2 - Answer -Increase hepatic gluconeogenes
