What is the primary function of glucocorticoids in glucose metabolism?

• A. Promote glucose production and enhance insulin sensitivity
• B. Inhibit glucose production and increase insulin sensitivity
• C. Promote glucose production and inhibit insulin sensitivity
• D. Regulate fat storage and decrease insulin production

Answer: (C)

Glucocorticoids play a crucial role in glucose metabolism, and their primary function is to promote glucose production in the liver through gluconeogenesis. This means that they facilitate the generation of glucose from non-carbohydrate sources, a vital process during times of stress or fasting when the body requires additional energy. Furthermore, glucocorticoids can antagonize the action of insulin, which leads to decreased insulin sensitivity. This resistance to insulin means that cells do not utilize glucose as effectively, leading to higher blood glucose levels. This process helps to ensure that glucose is available for energy, particularly in critical situations where immediate energy is needed. The focus on both promoting glucose production and decreasing insulin sensitivity makes this understanding of glucocorticoids essential, especially in conditions such as chronic stress or metabolic disorders, where glucose regulation becomes significant.
