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).

Explanation:

In pancreatic islets, alpha or A-cells constitute about 15% of pancretic islets cells and secrete glucagon. Its molecule consists of a single polypeptide chain of 29 amino acid residues. Glucagon intensifies glycogenolysis, deamination and gluconeogenesis and inhibits glycogenests in liver cells. It also intensifies lipolysis in adipose tissue. Thus, it is a promoter of catabolic metabolism.
