  1. ADH or vasopressin is
    1. enzyme that hydrolyses peptides
    2. hormone secreted by pituitary that promotes reabsorption of water from glomerular filtrate
    3. hormone that promotes glycogenolysis
    4. energy rich compound connected with muscle contraction.
Correct Option: B

ADH: Antidiuretic hormone – vasopressin is secreted by neurohypophysis (posterior lobe) of pituitary gland. This hormone increases the reabsorption of water from the urine and hence urine gets concentrated and ECF gets diluted. Diabetes insipidus caused by the hyposecretion of ADH.
