Solved in 2 steps
- Which of the following statements about insulin is true? Insulin acts as a transport protein, cany in g glucose across the cell membrane. Insulin facilitates the movement of inti acellular glucose transporters to the cell membrane. Insulin stimulates the breakdown of stored glycogen into glucose. Insulin stimulates the kidneys to reabsorb glucose into the bloodstream.What information can be inferred from this graph? rate of inherent mechanisms at which excess glucose is removed from blood average rate of excess glucose absorption and transport in blood rate of utilization of glucose by the tissues average blood glucose levels over a period of past two to 3 monthsWhich of the following statements about the integration of fat and carbohydrate metabolism control is correct? a. High insulin/glucagon ratio activates lipolysis in muscle b. High insulin/glucagon ratio inhibits lipogenesis in liver. c. Low insulin/glucagon ratio activates lipolysis in adipocytes. d. Insulin-dependent glucose transporters are recruited to their functional membrane site when insulin levels are low
- Which of the following is the primary process by which insulin stimulates glucose transport into adipose tissue cells?A) Activating Na+-K+ ATPaseB) Increasing synthesis of the glucose transporterC) Phosphorylating glucose to maintain the gradient of free glucose across the cellD) Promoting movement of the glucose transporter from the cytoplasm to the cell membraneEating non-fibrous carbohydrates can cause a cycle of glucose dependenceand hunger represented by a glucose crash. Explain this situation showing the levels of insulin and blood glucose under this situationThe Km of liver glucokinase is _____ than typical blood glucose concentrations. At typical blood glucose concentrations, therefore, the rate of glucose catabolism in liver cells is relatively ____. Much higher; fast Much higher; slow Much lower; fast Much lower; slow
- Which of the following statements about insulin istrue?a. Insulin acts as a transport protein, carryingglucose across the cell membrane.b. Insulin facilitates the movement of intracellularglucose transporters to the cell membrane.c. Insulin stimulates the breakdown of storedglycogen into glucose.d. Insulin stimulates the kidneys to reabsorbglucose into the bloodstreamAn individual has a genetic deficiency that prevents the production of glucokinase. Following a carbohydrate meal, do you expect blood glucose levels to be high, low, or about normal? What organ accumulates glycogen under these circumstances?Explain how blood glucose levels are maintained within a narrow range within the human body- you must ensure you cover the roles of both insulin and glucagon.
- How soon following acute abdominal pain due to pancreatitis is the serum amylase level expected to rise? 1) 1-2 hours 2) 12-24 hours 3) 6-12 hours 4) 3-6 hours no references, just homeworkDiscuss the four mechanisms by which blood glucose homeostasis is maintained.Fatty acids appear to stimulate insulin secretion to a much greater extent when glucose is also present.
