NURS 5315 Advanced Pathophysiology Ovarian cancer site of metastasis? Peritoneal surfaces, omentum (fold of peritoneum connecting the stomach with other abdominal organs), liver The increased NADH/NAD+ ratio in the liver from ethanol causes: 1. Pyruvate --> lactic acid, causing lactic acidosis 2. Oxaloacetate --> malate. This prevents gluconeogenesis and leads to hypoglycemia 3. Glyceraldehyde-3-phosphate --> glycerol 3- phosphate and combines with fatty acids to form triglyce...

What are the direct products of B-Oxidation? - 1) NADH, FADH2 used in ETC --> ATP 2) Acetyl-CoA i) substrate for ketogenesis ii) Allosterically activates pyruvate carboxylase --> gluconeogenesis 3) ATP used in anabolic process in fasted state i) Gluconeogenesis ii) Urea Cycle An 11-year-old girl is brought to the emergency department by her father. He reports she has recently been very thirsty and needing to make frequent trips to the bathroom. At her soccer game today, she compla...

Biochemistry Final Exam UNE CHEM 1005 (Weeks 9-15) Questions & Answers Solved 100% Correct!! Control of Fatty Acid Synthesis vs. Oxidation When Insulin is HIGH --> fatty acid synthesis occurs When Glucagon is HIGH --> lipolysis, fatty acid B-oxidation, ketogenesis occur **These never happen at the same time! Lipolysis Process of releasing free fatty acids from triacylglycerols stored in the adipose IN THE FASTED STATE Steps of lipolysis 1) Hormone Sensitive Lipase: activated by...

UNE FINAL BIOCHEM LATEST EXAM!! What are the main products of beta oxidation? 1 NADH, 1 FADH, 1 Acetyl CoA So in the case of an 11-year-old girl brought to the emergency department by her father, he's reporting that she's been very thirsty and needing to make frequent strips to the bathroom. Today, she reported lightheadedness during a soccer game and symptoms did not resolve after drinking a power beverage. A rapid dipstick test revealed glucose in her urine and further diagnosis are con...

What is the role of adipose in metabolism? - ANSWERSStorage of triacylglycerols as a source of energy that can be released as FFAs under fasted state conditions; other roles include body weight homeostasis, coagulation, immunity, vascular tone control, appetite regulation, glucose/lipid metabolism, reproduction, angiogenesis what are the direct products of B-oxidation? - ANSWERSNADH + FADH2 (used in ETC to produce ATP), Acetyl CoA (substrate for ketogenesis, allosteric activator of pyruvate c...

UNE Biochem FINAL |83 Questions| With 100% Verified & Passed Solutions. An individual goes to bed around 8 pm and doesn't wake up until 9 am the next morning. During this time, which of the following is the primary oxidizable substrate in the skeletal muscle? Free fatty acids Under fasted conditions as described above, the skeletal muscle and liver would be oxidizing free fatty acids as a means of producing ATP. A well, 2-year-old girl presents to the clinic with symptoms of a viral ill...

Under fasting conditions (ratio of insulin to glucagon <1), elevated glucagon will activate which of the following enzymes? - Hormone sensitive lipase The process of ketogenesis refers to the conversion of acetyl CoA to which of the following compounds? - D-3-hydroxybutyrate or B-hydroxybutyrate During the fasted state, lipolysis is facilitated by the action of hormone sensitive lipase. This enzyme requires which of the following post - translational modification for activation? -...
