Marianne has type 1 diabetes. One day, after accidentally injecting herself with too much insulin, she starts to shake and feels confused. Following her doctor's suggestion, she drinks a glass of orange juice- a steady source of glucose- and soon her symptoms subside. What caused her symptoms? How would a glucose-rich snack help?

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.

Mr. M is a patient with type I diabetes mellitus. He presents with dizziness, rapid breathing, confusion, and weakness. You find out that he forgot to inject his normal dose of insulin this morning. Will his blood glucose concentration be normal? Explain. Your colleague suggests that Mr. Montez needs to ingest some sugar. Is this going to help him? Why or why not?
Explain the functions of insulin. Why do you think a hormone such asinsulin is required to carry out these functions?
Would a metabolic rational for a child who has a similar diet to other children but after infections or vigorous exercise has low blood glucose levels and increased lactic acid in the blood along with potential lethargy, shakiness and irritability be type 1 diabetes? Noting that an effective treatment for them is alanine supplementation in the diet.
In patients with type 2 diabetes, cells no longer respond to the hormone insulin. What change has likely occurred in these cells to make them insulin resistant?
In type II diabetes, insulin is produced but is nonfunctional. These individuals are described as “starving in the sea of plenty” because their blood glucose levels are high, but none of the glucose is transported into the cells. Describe how this leads to malnutrition.
Why do you suppose individuals with diabetes must receive insulin subcutaneously by injection rather than orally?
For our patient John with diabetes type II, he can make insulin but his body cells can be resistant to this insulin. Note: activated insulin receptors will activate glucose receptors. How is John’s diabetes related to the endocrine system?
