Chapter 37.4, Problem 2TYK
Gluconeogenesis
- occurs when the liver synthesizes glucose from noncarbohydrate precursors.
- is the process by which glycogen is broken down to glucose.
- occurs primarily when an animal is in the absorptive state.
- occurs when triglycerides are being formed and stored in adipose cells.
- occurs primarily in skeletal muscle.

- Which of the following is TRUE regarding liver metabolism? Select three of the following: The liver (hepatocytes) has hundreds of functions, such as producing glucose, ketones, fatty acids, cholesterol, proteins, and bile for the rest of the body. Hepatocytes have the GLUT2 antiporter, which allows for secondary active transport of glucose into the cells. Hepatocytes have glucokinase that continually makes glucose 6-phosphate, and it has a lower Km than other hexokinases so it continuously metabolizes glucose when concentrations are low. Glucose 6-phosphate is the "transfer station" in the liver since it can be made my multiple pathways and have multiple fates. The liver converts amino acids to citric acid cycle intermediates or pyruvate for gluconeogenesis. The liver oxidizes fatty acids into glucose, which can be sent to other cells and used for energy or converted into phospholipids and triacylglycerol.arrow_forwardWhat are the 3 macronutrients and how do each provide energy to the body? Define the fed, post-absorptive, fasting, and starved states. Outline changes in the utilization of glucose, fatty acids, amino acids, and ketone bodies as the body transitions from the fed state to the prolonged starvation state. Describe the impacts of insulin, glucagon, epinephrine, and cortisol on CHO, lipid, and protein metabolism. Describe the major pathways that occur in the liver, muscle, adipose tissue. Describe which hormones exercise tends to increase and potential impacts on pathways we’ve discussed. Describe the cori cycle and the glucose-alanine cycle. Describe differences in primary fuel sources by exercise intensity. Describe classical vs moderate CHO loading in preparation for competition in trained athletes. Simple to the point answers please!arrow_forwardIndicate whether the following metabolic processes primarily occur during the FED STATE or FASTED STATE. 1. Release of insulin 2. Release of glucagon 3. Glycolysis 4. Glycogenesis 5. Gluconeogenesis 6. Lipogenesis 7. Glycogenolysis 8. Lipolysis 9. Glucose release 10. Glucose uptakearrow_forward
- The body doesn’t have a reserve of proteins or amino acids for energy production. Which class of protein may be used initially during fasting to maintain glucose and energy levels? What is the difference between a glucogenic and ketogenic amino acid and why are both important during fasting?arrow_forwardWhich of the following statements about the ketone bodies is/are TRUE? Produced during starvation and in diabetic patients Excess is transformed to acetone or hydroxybutyrate. Extreme amount of ketone bodies may cause ketosis in diabetics. Occurs during a high-lipid and low-protein diet.arrow_forwardWhich of the following are mechanisms that prevent the liver from using up glucose that is more urgently required by other tissues? (select all that apply) Group of answer choices Glucokinase (the liver's version of hexokinase) has a lower affinity for glucose than hexokinase does GLUT2 has a lower affinity for glucose than GLUT4 does The liver produces insulin when blood glucose levels are low The liver does not express a phosphofructokinase enzyme The liver increases glycolysis in response to glucagonarrow_forward
- Which of the following processes would happen on a large scale during starvation (and not in a person who eats regularly)? Chylomicrons deliver lipids to adipose (fat) cells Gluconeogenesis in the liver and kidney; glucose is secreted into blood Protein catabolism in muscle cells; liberated amino acids are funneled into the Krebs cycle Triglycerides previously stored in adipose tissue undergo lipolysis; glycerol is used by the liver for gluconeogenesisarrow_forwardHow do glucagon and epinephrine affect glycogen in the liver? They increase both glycogen breakdown and gluconeogenesis. They increase both glycogen breakdown and glycolysis. They increase glycolysis to breakdown glucose. They increase glycogenin synthesis.arrow_forwardWhich weight loss suggestion will lead to an increased need for gluconeogenesis? Atkins Diet Exercise High fiber diet Herbal treatmentsarrow_forward
- which of the following is not true for a muscle that is forced to metabolize glucose anaerobically ? - The cells breakdown glucose faster - The cells produce less ATP per mole of glucose - The cells metabolize glucose to lactate - The activity of the cytosolic gycerol-3-phosphate dehydrogenase will be required for the muscle to sustain glycolysis - The muscle quickly experiences fatigue if it is deficient in the enzyme lactate dehydrogenasearrow_forwardWhich of the following statements regarding gluconeogenesis is NOT true: It utilizes all of the same enzymes as glycolysis. It results in production of glucose from pyruvate. It consumes ATP. It involves one or more intermediates that are different from those of glycolysis.arrow_forwardMrs. Salma, a 55-year-old diabetic patient, experiences slow wound healing and peripheral neuropathy. Investigation reveals alterations in the Pentose Phosphate Pathway. How might dysregulation in the PPP contribute to complications such as slow wound healing and peripheral neuropathy in diabetic patients? Impaired nucleotide synthesis. Elevated insulin sensitivity. Lactic acid accumulation. Reduced oxidative stress.arrow_forward
