Question

Which of the following glands prevents diabetes?
A) Pancreas
B) Pituitary
C) Adrenal
D) Testis

Answer 1

Hint: Diabetes occurs when there is irregular production of insulin or unusable insulin in the body. Insulin is secreted by the pancreas which carries blood sugar to cells of the body.

Step by step answer: Pancreas is the important endocrine organ which secretes many enzymes that control digestion and also the blood glucose. The blood glucose is regulated by the secretion of the enzyme insulin in the body. The beta cells in the lining of the pancreas secrete insulin when there is an increase in blood sugar. It is done to maintain homeostasis. The insulin is first created or translated as preproinsulin and then a proinsulin form is created. This is cleaved to form insulin and this is stored in the beta cells. The insulin carries all the excess glucose to the cells which will be required for energy production. It can also be circulated to the liver for storage of glucose in the condensed form known as glycogen. The glucose from the diet is supplied in the blood for transportation. The increase or decrease in levels of glucose can trigger the release of one of the enzymes of the pancreas. Diabetes is caused by the increase in blood sugar level where either there is no insulin secretion or no insulin production or abnormal activity of insulin. This results in a lack of regulation of blood sugar.
Hence, the correct answer is option A.

Note: The pancreas also has alpha cells in the lining of the organ which secretes glucagon. Glucagon increases the sugar content in the body when there is a decrease in sugar level. This initiates the breakdown of the glycogen in the liver giving sugar molecules.
