Options
- AGlucagon - Beta cells (source)
- BSomatostatin - Delta cells (source)
- CCorpus luteum - Relaxin (secretion)
- DInsulin - Diabetes mellitus (disease)
Correct answer
A. Glucagon - Beta cells (source)
Step-by-step solution
In pancreatic islets, alpha or A-cells constitute about 15 % of pancreatic 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 glycogenesis in liver cells. It also intensifies lipolysis in adipose tissue. Thus, it is a promoter of catabolic metabolism.
