Question

During summer, the levels of _________ hormone is maintained at high level.

• A. Glucagon
• B. ADH
• C. Insulin
• D. Relaxin

Answer 1

The correct option is B ADH

A. Glucagon is secreted from alpha cells of islets of Langerhans of pancreas. It increases blood sugar level by stimulating glycogenolysis (i.e. break down of glucose) and gluconeogenesis (synthesis of glucose).

B. ADH (Anti diuretic hormone )or Vasopressin is secreted from the posterior part of pituitary gland. This hormone increases reabsorption of water in kidneys and this results in decreased rate of urine production.

C. Insulin is secreted from the β cells of islets of Langerhans of pancreas. Insulin acts on hepatocytes and adipocytes and increases the uptake of cellular glucose and its utilisation.

D. Relaxin is a protein hormone secreted by placenta. It dilates the cervix and aids in childbirth.

During summers, ADH hormone is maintained at high level so that water is reabsorbed in more quantity from kidneys and thus, prevents dehydration.

So, the correct answer is 'ADH'.
