Question

Which one of the following pairs is incorrectly matched?

• A. Glucagon - Beta cells (source)
• B. Somatostatin - Delta cells (source)
• C. Corpus luteum - Relaxin (secretion)
• D. Insulin - Diabetes mellitus (disease)

Answer 1

The correct option is A Glucagon - Beta cells (source)

Glucagon is secreted by $\alpha$-cells of the islets of Langerhans in the pancreas. It increases the concentration of glucose in the blood by stimulating the breakdown of glycogen.
$\beta$-cells of the islets of Langerhans in the pancreas secrete insulin which helps stimulate metabolism of carbohydrates. Hypo-secretion of this hormone causes diabetes mellitus.
Relaxin, which is secreted by the Corpus luteum, ​​​​​relaxes the ligaments of pelvic girdles at the time of birth.
