Question

ADH or vasopressin is

• A. enzyme that hydrolyses peptides
• B. hormone secreted by pituitary that promotes reabsorption of water from glomerular filtrate
• C. hormone that promotes glycogenolysis
• D. energy rich compound connected with muscle contraction.

Answer 1

Answer: (B)

Antidiuretic hormone (ADH) or vasopressin is secreted by the posterior lobe of the pituitary gland. It increases the reabsorption of water in the distal convoluted tubule, collecting tubules and collecting ducts of the nephrons of the kidneys. As a result, the reabsorption of water from the glomerular filtrate is increased. Enzyme that hydrolysis peptides is known as peptidase. Hormones that promotes glycogenolysis is glucagon and adrenaline. Energy rich compound connected with muscle contraction is ATP.
