BCH4024 11724 OC F24 E3 Q35: A young girl with a history of intense abdominal pain was taken to her local hospital in severe distress. Blood was drawn, and the plasma appeared milky, with triacylglycerides (TAG) level in excess of 2000 mg/dl (normal = 4-150 mg/dl). It is determined that exogenous pathways are likely affected. Which of the following lipoprotein particles is most likely responsible for the appearance of the patient’s plasma?

BCH4024 11724 OC F24 E3 Q12: Suppose you discovered a mutant yeast whose glycolytic pathway was shorter because of a new enzyme catalyzing the reaction: What would be the result of shortening the glycolytic pathway in this manner?

BCH4024 11724 OC F24 E3 Q42: During fasting, which process is responsible for maintaining blood glucose levels by generating glucose from non-carbohydrate sources? 

BCH4024 11724 OC F24 E3 Q46: Succinyl-CoA is a product of an enzyme of the citric acid cycle. That enzyme is ________________.

BCH4024 11724 OC F24 E3 Q38: What is the primary purpose of the pentose phosphate pathway in carbohydrate metabolism? 

BCH4024 11724 OC F24 E3 Q47: You perform an experiment with three preparations of intact mitochondria, Prep1, Prep 2, and Prep 3. You treat the preparations as follows: Prep 1 Add succinate (oxidizable substrate) Prep 2 Add succinate and an uncoupler such as dinitrophenol, DNP Prep 3 Add succinate and oligomycin  You organize your data in the following table of results (assume all other substrates are available): What would be the results for Prep 3?

BCH4024 11724 OC F24 E3 Q21: Which of the following statements about glycogen metabolism is TRUE?

BCH4024 11724 OC F24 E3 Q14: Glycogen phosphorylase-a catalyzes the nucleophilic attack and cleavage on the glycosidic bonds of the glycogen particle. Which bond(s) is/are cleaved, and what is the product of one cleavage reaction?

BCH4024 11724 OC F24 E3 Q40: The next two questions deal with the following case: A 10-year-old boy is brought to the emergency department by his mother.  He came home from school, had a snack, and his mother found him unconscious in the bathroom a short time later.  She tells you he is newly diagnosed with type I diabetes. Blood glucose levels are low, suggesting the child had taken his insulin.   At the time of these symptoms, which of the following enzymes is paired with the correct allosteric inhibitor?

BCH4024 11724 OC F24 E3 Q1: You see a patient in your clinic who complains that they are unable to carry out long, intensive exercise. You have a muscle biopsy performed, and the results indicate a deficiency in the enzyme that catalyzes the following reaction. What is the enzyme, and why does a deficiency of this enzyme lead to rapid muscle fatigue?
