Correct Answer is C
Explanation
In type 2 diabetes, insulin resistance occurs, meaning that the body's cells do not respond effectively to the action of insulin. This leads to decreased glucose uptake by cells and elevated blood sugar levels.
Incorrect choices:
a. This choice is incorrect. Autoimmune destruction of pancreatic beta cells is characteristic of type 1 diabetes, not type 2.
b. This choice is incorrect. Increased sensitivity of cells to insulin would result in improved glucose uptake and reduced hyperglycemia.
d. This choice is incorrect. Excess insulin production by the pancreas is not a typical mechanism in type 2 diabetes.
Correct Answer is C
Explanation
Prolonged hyperglycemia in diabetes can lead to the formation of advanced glycation end products (AGEs), which contribute to tissue damage, inflammation, and complications such as neuropathy and nephropathy.
Incorrect choices:
a. This choice is incorrect. Hypoglycemic episodes are associated with low blood sugar, not prolonged hyperglycemia.
b. This choice is incorrect. Increased cellular glucose uptake and energy production would not be consequences of prolonged hyperglycemia; rather, hyperglycemia impairs cellular glucose uptake.
d. This choice is incorrect. Prolonged hyperglycemia leads to insulin resistance, not enhanced insulin sensitivity.
