Answer #1

Ans.a. Shrinkage of cells

b.Decreased plasma volume

c. Positive Sodium balance

Vasopressin or Antidiuretic hormone is secreted from posterior pituitary in response to increased plasma osmolarity or decreased plasma volume

It binds to receptors on cells in the collecting ducts of the kidney and promotes reabsorption of water back into the circulation.

Antidiuretic hormone stimulates water reabsorbtion by stimulating insertion of "water channels" or aquaporins into the membranes of kidney tubules. These channels transport solute-free water through tubular cells and back into blood, leading to a decrease in plasma osmolarity.

Vasopressin, a nonapeptide hormone secreted by the pituitary gland, functions by stimulating the kidney to retain water. Its sequence was determined by the following evidence: 1. Vasopressin is a cyclic compound containing a disulfide bridge between two cysteine residues. 2. When the disulfide bridge is reduced, vasopressin has the constitution Arg, Asn, Cys2, Gln, Gly, Ile, Phe, Pro. 3. Partial hydrolysis of vasopressin yields seven fragments: Asp-Cys, Ile-Glu, Cys-Phe, Arg-Gly, Phe-Ile-Glu, Glu-Asp-Cys, Cys-Pro-Arg. 4. Gly is the C-terminal group. 5....
