QUESTIONS AND CORRECT ANSWERS
Which type of Diabetes involves insulin resistance where the effect of insulin is blunted in skeletal muscle and liver?
- ✔✔✔Type 2 Diabetes Mellitus
Which type of Diabetes involves the destruction of pancreatic beta cells and results in an absolute deficiency of
insulin? - ✔✔✔Type 1 Diabetes Mellitus
What type of Diabetes is also called 'Juvenile diabetes,' and is an autoimmune disorder resulting from genetics,
environmental trigger, hypersensitivity reaction? - ✔✔✔Type 1 Diabetes Mellitus
Which type of Diabetes involves progressive impairment of beta cells, deranged secretion of insulin, or the eventual
exhaustion/failure of beta cells, and increased glucose production by liver? - ✔✔✔Type 2 Diabetes Mellitus
The following risk factors are for what disease?

,Pathophysiology of type 2 diabetes 2026
-Hypertension
-Polycystic Ovary Syndrome
-Latino/Hispanic, Black, Asian American, Native American, or Pacific Islander decent
-History of delivering infant >9 Ibs. - ✔✔✔Type 2 Diabetes Mellitus
What is the pathophysiology of Type 2 Diabetes Mellitus? - ✔✔✔Regardless of cause,
1. pancreatic beta cells have decreased release of insulin (leads to decreased glucose uptake AND increased hepatic
glucose output and eventual hyperglycemia).
2. Skeletal muscle has increased insulin resistance (leads to decreased glucose uptake, and eventual hyperglycemia).
The following risk factors are for what disease?
-Family history
-Beta cell autoimmunity
-Autoimmune disease
