Q. 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)
Explanation
In pancreatic islets, alpha or α-cells constitute about 15% of pancreatic islets cells and secrete glucagon. 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.
