11. What would happen if the pancreas is defective : [R.A.S./R.T.S. (Pre) 1992]

Correct Answer: (b) Insulin and glucagon are not formed.
Solution:The pancreas is a mixed gland which secretes digestive enzyme while beta cells of its islets of Langerhans secrete insulin, alpha cells secrete glucagon and delta cells secrete somatostatin hormone. If the pancreas is defective by any of the reason, then the formation of insulin and glucagon are affected badly.

12. Which one of the following hormones stimulates pancreas for the production of digestive juice ? [U.P.P.C.S. (Pre) 1996]

Correct Answer: (c) Secretin
Solution:Secretin is a hormone that stimulates pancreas for the production of digestive juice. Secretin also helps to regulate the pH of the duodenum by inhibiting the secretion of gastric acid from the parietal cells of the stomach.

It also stimulates the contraction of the pancreas. It is a peptide hormone produced in the S cells of the duodenum. It also regulates secretions in the stomach and liver.

13. Insulin is : [60ᵗʰ to 62ⁿᵈ B.P.S.C. (Pre) 2016]

Correct Answer: (d) Protein
Solution:Insulin is a protein chain or peptide hormone produced by the beta cells of the pancreatic islets of Langerhans and it is considered to be the main anabolic hormone of the body.

In chemical terms it is a micro peptide that is composed of 51 amino acids. It regulates the metabolism of carbohydrates, fats and protein by promoting the absorption of glucose from the blood into liver, fat and skeletal muscle cells in the body.

14. Which of the following hormones is secreted by the Beta cell of Islet of Langerhans of Pancreas? [U.P.C.S. (Pre) 2023]

Correct Answer: (c) Insulin
Solution:

Insulin hormones is secreted by the Beta cells of Islets of Langerhans of Pancreas. It regulates the metabolism of carbohydrates, fats and protein by promoting the absorption of glucose from the blood into liver, fat and skeletal muscle cells.

When the body digests food rich in carbohydrates, glucose is released into the bloodstream. This leads to an increase in blood glucose levels in the body. Consequently, the pancreas sends chemical signals in the form of insulin that direct all the cells in the body to take in the glucose.

Most of this glucose is used up to provide energy to the cells. The excess glucose in the bloodstream is converted into glycogen and absorbed by the liver and muscle cells to be used later. Ultimately, Insulin release lowers blood glucose levels.

15. In human system, insulin controls the metabolism of : [63ʳᵈ B.P.S.C. (Pre) 2017]

Correct Answer: (e) None of the above/More than one of the above
Solution:

Insulin hormones is secreted by the Beta cells of Islets of Langerhans of Pancreas. It regulates the metabolism of carbohydrates, fats and protein by promoting the absorption of glucose from the blood into liver, fat and skeletal muscle cells.
