Q1. A 45-year-old man with type 2 diabetes has a fasting blood glucose level of 180 mg/dL. Which mechanism is primarily responsible for the increase in blood glucose levels?
Answer: Insulin resistance
Explanation: Insulin resistance leads to impaired glucose uptake in peripheral tissues, causing blood glucose levels to increase, unlike glucagon suppression, pancreatic beta-cell insulin secretion, and hormonal regulation of gluconeogenesis.
