Which of the following best describes type 1 diabetes mellitus?
Insulin resistance and relative insulin deficiency.
Onset typically occurs in adulthood.
Caused by an autoimmune destruction of pancreatic beta cells.
Mainly managed through oral hypoglycemic agents.
The Correct Answer is C
Type 1 diabetes mellitus is characterized by an autoimmune destruction of pancreatic beta cells, leading to an absolute insulin deficiency. It is not primarily characterized by insulin resistance (choice a) and is not typically diagnosed in adulthood (choice b). Oral hypoglycemic agents (choice d) are not the mainstay of treatment for type 1 diabetes.

Correct Answer is B
Explanation
Insulin is a hormone produced by the pancreas that plays a crucial role in regulating blood glucose levels. It facilitates glucose uptake into cells, promotes glycogen synthesis in the liver and muscles, and inhibits hepatic glucose production.
Incorrect choices:
a. This choice is incorrect. Glucagon is another pancreatic hormone that increases blood glucose levels by promoting glycogen breakdown and glucose release from the liver.
c. This choice is incorrect. Epinephrine is a hormone produced by the adrenal glands that can raise blood glucose levels during times of stress.
d. This choice is incorrect. Cortisol, also produced by the adrenal glands, can increase blood glucose levels in response to stress and inflammation.
Correct Answer is A
Explanation
Metformin is a commonly used oral antidiabetic medication that improves insulin sensitivity in peripheral tissues, reduces hepatic glucose production, and enhances glucose uptake by cells.
Incorrect choices:
b. This choice is incorrect. Glipizide is a sulfonylurea medication that stimulates insulin secretion from the pancreas, rather than increasing insulin sensitivity.
c. This choice is incorrect. Insulin lispro is a rapid-acting insulin analog used for mealtime coverage in insulin therapy.
d. This choice is incorrect. Exenatide is a glucagon-like peptide-1 (GLP-1) receptor agonist that stimulates insulin secretion and suppresses glucagon release, but it does not primarily target insulin sensitivity.
