Which hormone is secreted by the pancreas to help lower elevated blood glucose levels?

💡 Solution & Explanation

Insulin is a peptide hormone secreted by the beta cells of the islets of Langerhans in the pancreas to lower blood glucose by facilitating cellular uptake. Glucagon performs the opposite function by raising blood sugar levels when they drop too low. Deficiencies in insulin production lead to diabetes mellitus, a common lifestyle disorder tested frequently in civil services exams.
