during fasting to fullfill the body glucose requirment gluconeogenesis take place .
synthesis of glucose from glycerol , pyruvate , lactate and son on .
glycogen breakdown to produce glucose through gylcogenolysis.
glucagon are the hormone which are involved in promoting glycogen breakdown.
glycogenolysis | inhibit insulin | stimulate glucagon |
gluconeogenesis | inhibit insulin | stimulate glucagon |
once the glucose is obtained it further undergo glycolysis to yield pyruvate which further yield acetyl CoA .
acetyl CoA enter the kreb cycle to yield ATP.
glycolysis | stimulate insulin | inhibit glucagon |
Question #8 (10 points) - During fasting, explain what happens for carbohydrate metabolism (glycogen synthesis/breakdown; glucose...
Which of the following statements about hormonal regulation of glycogen synthesis and degradation are correct? Multiple answers! A. Insulin increases the capacity of the liver to synthesize glycogen. B. Insulin is secreted in response to low levels of blood glucose. C. Glucagon and epinephrine have opposing effects on glycogen metabolism. D. Glucagon stimulates the breakdown of glycogen particularly in the liver. E. The effects of all three of the regulating hormones are mediated by cAMP.
16. Briefly describe the action of Insulin on carbohydrate metabolism, fat metabolism, and on protein metabolism. I.e. do es it promote (+) or discourage (-) the following? a. Glycogenesis (production of glycogen) b. Glycogenolysis (breakdown of glycogen) c. Glycolysis: using glucose for fuel inside cells d. Gluconeogenesis: Production of glucose by liver (usually from aa) e. Uptake of glucose into fat and muscle cells? f. Lipid synthesis: Production of Triglycerides in fat cells g. Lipid breakdown/mobilization of fat from adipocytes(breakdown...
Question 5 3 pts What is the role of UDP-glucose in glycogen synthesis? O UDP-glucose reacts with a glycogen chain and extends its length by one glucose unit. O UDP-glucose adds a glucose unit to UTP O UDP glucose reacts with ATP to form UTP All of the above. Question 6 3 pts What is the role of "glucagon- and epinephrine-triggered cAMP cascades" in regulating or influencing glycogen synthesis? O These cascades turn on or stimulate glycogen synthesis. O These...
Compare and contrast glycogen metabolism in the liver during fasting to glycogen metabolism in the skeletal muscle during exercise. What is unique about muscle glycogen metabolism
Model 2 - Feedback Control of Blood Glucose Pancreas .. Liver Other cells OO Blood glucose is too high. Cycle A Blood glucose drops. Baseline blood glucose level. Blood glucose rises. Glucose Insulin Glycogen Glucagon Cycle B Blood glucose is too low. 7. Where in the body does insulin and glucagon originate? 8. In what form is glucose stored in the liver and what is the consequence in terms of glucose blood levels? 10. Which hormone (insulin or glucagon) helps...
20. What happens when beta cells of the pancreas release insulin into the blood? glucose levels rise to a set point and stimulate glucagon release. b) Body cells take up more glucose. c) The liver breaks down glycogen to glucose. d) Alpha cells are stimulated to release glucose into the blood óth B and D are correct.
Part A - Regulatory Hormones Before exploring hormones that regulate blood glucose, you must first be able to use the vocabulary effectively. In this activity, match the correct term with the sentence that describes the structure or function involved in blood glucose regulation. Match the words in the left column to the appropriate blanks in the sentences on the right. View Available Hint(s) ResetHelp 1. Insulin is produced in and released from the ---. 2. In response to insulin or...
Question 43 During fasting, all of the following occur, except o appetite is supressed glucose is used to build glycogen stores fat is broken down to provide energy o metabolism slows Previous Question 47 2 pt Of the major minerals, the three that function in the mineralization of bones are Phosphorus, Magnesium, Calcium Sodium, Calcium, Phosphorus Calcium, Phosphorus, Chloride O Magnesium, Calcium, Potassium
1. What is happening in a healthy individual about an hour into a glucose tolerance test? (Note: At this early time-point, blood glucose levels are still high. Also, remember that a person who is taking a glucose tolerance test was fasting for 12 hours prior to the test!) (Select ALL that apply!) Hint: Review pages 319-325, 462-467 and 489-491 of Tymoczko 3E before attempting this question. A. Glucose is being exported by the liver B. Glucose is being taken up...
