Antidiuretic hormone (adh) targets kidney cells and blood vessels, whereas growth hormone (gh) targets many different kinds of cells throughout the body. which of the following is the best explanation for this observation?

a. the gh receptor is expressed in many different cells, whereas the receptor for adh is expressed primarily in kidney select blood vessel cells.
b. adh is a local regulator, and gh is not.
c. adh and gh are produced by different endocrine organs.
d. adh is a peptide hormone, whereas gh is a protein hormone.

The correct answer is a The GH receptor is expressed in many different cells whereas the receptor for ADH is expressed primarily in kidney select blood vessel cells.

Explanation:

Growth hormone helps in the growth and development of different kinds of cells and tissues of our body such as bone cell,liver cell,muscle cell etc.Whereas anti diuretic hormone act only on the corticle collecting ducts of the nephron to increase the permeability of the later to water.

  Thus ADH or Antidiuretic hormone play an important role in water reabsorption.
