QuestionAnswer
production of glucose from non-carbohydrate sources
T/F: Chronic hyperinsulinemia causes a downregulation of insulin receptors due to an imbalance of receptor internalization and recycling.
these cells of the pancreas make insulin
GI hormones that are released in response to a meal containing glucose
T/F: An increase in sympathetic activity, increases production and synthesis of insulin.
Currently used in the treatment of diabetes and they act by binding to their G-protein coupled receptor to increase intracellular Ca activating insulin release.
These drugs act on the ATP dependent K channel to activate insulin secretion
T/F: Acute hypoglycemia cause neurological problems, coma, and death because the brain is dependent upon glucose as a source of energy.
low levels of glucose stimulates the release of _____.
IRS mediates the translaocation of what glucose transporter to the cellular membrane?
In liver, glucose stimulates which enzyme?
percentage of beta cells in the pancreas
T/F: Proinsulin is composed of 2 subunits.
insulin dependent transporter
T/F: Insulin is protein hormone and is synthesized from pro-insulin.
How much oral glucose is administered during a glucose tolerance test? (grams)
This protein is important for the activation of glucose transport and it is phophorylated by the B subunit of the insulin receptor.
acetylcholine acts to _____ insulin secretion
persistent hyperglycemia causes perisistent _______.
T/F: 98% of the pancreas has endocrine function.
Normal blood glucose levels are ___mg/ dl

Major targets of insulin include liver, _____ and _____
QuestionAnswer
T/F: Insulin receptor is a tyrosine kinase receptor thats acts to autophosphorylate itself.
insulin deficiency causes a (an) _____ in plasma glucose
T/F: Hepatocytes contain GLUT4 transporters.
T/F: Influx of glucose in a hepatocyte activates glucokinase which increase ATP levels, activating ATP dependent K channel. This causes a depolarization of the cell causing an incr
T/F: Insulin's response to persistent hyperglycemia is characterized by a sharp initial increase in insulin secretion, then a fall and gradual rise in insulin (due to increase in i
