Regular insulin MOA?

• A. Controls postprandial hyperglycemia or basal glycemic control
• B. Decreases hepatic glucose production
• C. Increases glucose secretion in urine
• D. Mimics incretin hormones

Answer: (A)

Regular insulin works by replacing or supplementing the body's own insulin, signaling body tissues to take up glucose and telling the liver to reduce glucose production. This combination lowers blood sugar during fasting and after meals, helping keep levels in a steady range.

That broad effect—controlling glucose levels in the fasting (basal) state and after meals (postprandial)—best describes the action of regular insulin. Decreasing hepatic glucose production is indeed a part of how insulin works, but describing the MOA as that single effect is too narrow and doesn’t fully capture the overall goal of insulin therapy. Insulin does not increase glucose loss in urine, and it does not mimic incretin hormones, which are different gut-derived signals that enhance insulin secretion.
