Major targets of insulin include liver, _____ and _____
T/F: Proinsulin is composed of 2 subunits.
Muscle and adipocytes contain GLUT4.
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
How much oral glucose is administered during a glucose tolerance test? (grams)
The liver degrades ___% of the insulin released.
these cells of the pancreas make glucagon
percentage of delta cells in the pancreas
insulin dependent diabetes
used as a measure of insulin secretion
insulin independent diabetes
The B subunit of the insulin receptor acts to bind and recognize insulin.
T/F: 98% of the pancreas has endocrine function.
Dr. Benting won the nobel prize for insulin in ____.
percentage of alpha cells in the pancreas
insulin independent transporter
T/F: Acute hypoglycemia cause neurological problems, coma, and death because the brain is dependent upon glucose as a source of energy.
These drugs act on the ATP dependent K channel to activate insulin secretion
What other 2 molecules can be found in mature insulin granules besides insulin?
T/F: Insulin is protein hormone and is synthesized from pro-insulin.
percentage of beta cells in the pancreas
these cells of the pancreas make somatostatin

insulin deficiency causes a (an) _____ in plasma glucose
acetylcholine acts to _____ insulin secretion
Normal blood glucose levels are ___mg/ dl

T/F: C peptide has no biological funtion.
T/F: Glucose enters the cell via active transport.
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.
T/F: Chronic hyperinsulinemia causes a downregulation of insulin receptors due to an imbalance of receptor internalization and recycling.
