Figure 37.11 Pancreatic tumors may cause excess secretion of glucagon. Type I diabetes results from the failure of the pancreas to produce insulin. Which of the following statement about these two conditions is true? A pancreatic tumor and type I diabetes will have the opposite effects on blood sugar levels. A pancreatic tumor and type I diabetes will both cause hyperglycemia. A pancreatic tumor and type I diabetes will both cause hypoglycemia. Both pancreatic tumors and type I diabetes result in the inability of cells to take up glucose.
Low insulin levels and low plasma amino acid levels Protein Catabolism Olher amino acids alpha-KG Glutamate Giutamne Gutamine Glutamate SO H Cystie)ine EGSH Cystfe)ineCyst(eline- Urea Skeletal Muscle Liver To the best of your abilities, explain the image above. Do not include other "unnecessary" things that you cannot see in the picture.
Which of the following enzymes are activated after insulin binds to its receptor? (select all that apply) Protein Phosphatase-1 Glycogen Synthase Lipase Acetyl CoA Carboxylase Glycogen phosphorylase Glycogen phosphorylase kinase
Which of the following are true about how pancreatic β cells sense blood glucose levels and release insulin? (select all that apply) Group of answer choices The first step of glycolysis (producing glucose 6-phosphate) is more efficient in pancreatic β cells than in muscle glucose transporters in pancreatic β cells have a higher affinity for glucose than the transporters in other tissues Increased production of ATP is used as a signal that blood glucose is high Insulin is released when blood glucose levels are high Increases in ATP open a K+ channel Influx of Ca2+ stimulates insulin release
If a healthy individual (without diabetes I or diabetes II) is given an insulin injection, what would be the potential outcome (select all that apply) blood glucose levels would decrease drastically glycogen storages in liver and muscle would increase glycogen storages in liver and muscle would decrease potential death due to hypoglycemia potential death to do hyperglycemia blood glucose levels would increase drastically
Match the molecule involved in insulin signaling with what it does insulin receptor [Choose ] [Choose] physically pushes glucose out of the cell physically brings glucose into the cell binds to insulin and sends signal to cell a protein hormone that signals cells to import glucose signals cells to export glucose a carbohydrate taken into cells as an energy source glucose insulin glucose transporter [ Choose ] 近
Which changes would be expected in a normal human after a meal rich in carbohydrates (select all that apply)? O increased secretion of the pancreatic hormone, insulin O increased glucose uptake in myocytes via glucose transporters increased activity of glucose 6-phosphatase in hepatocytes O increased activity of the liver enzyme, glucokinase O increased activity of GSK-3 in both myocytes and hepatocytes
Which of these enzymes/complexes will insulin activate in the liver? Choose all that apply. Glycogen synthase Glycogen phosphorylase Acetyl-CoA carboxylase Carnitine shuttle PFK-1 FBPase-1
All of the following statements concerning glycogen synthesis and glycogenolysis are true EXCEPT High blood glucose and high insulin will activate glycogen synthesis and inhibit glycogen phosphorylase. Taking this test will activate glycogen phosphorylase and inhibit glycogen synthase. Being hit in the head with a bat will activate glycogen synthesis and inhibit glycogen phosphorylase. A low insulin to glucagon ratio will activate glycogen phosphorylase and inhibit glycogen synthase. Exercise will activate glycogen phosphorylase and inhibit glycogen synthase.
A patient has an insulin sensitivity factor of 1 unit of insulin per 30 mg/dl over 110 mg/dl. If their blood glucose prior to a meal is 220 mg/dl, how much insulin do they need to inject? (round to the nearest unit)
People with non-insulin-dependent diabetes mellitus are generally not ketosis prone. This is thought to be a result of: the lack of increase in glucagons in the se individuals the presence of insulin in the individuals their obesity the fact that, their blood glucose levels do not tend to rise significantly Metabolic actions of insulin include all of the following except: increased glycogenesis decreased gluconeogenesis increased basal metabolic rate increased skeletal muscle amino acid up-take all of the above are metabolic actions of insulin
Which 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 glucagon
