Answer:

Only small number of the cells in the body are the target cell for the aldosteron

Step-by-step explanation:

Target cell for a certain hormone is a cell that have hormone receptor specific for that hormone. There are two main types of receptors on target cell:

  • cell membrane receptors (also called trans membrane receptors)-usually for peptide hormones, such as insulin
  • intracellular receptors (also called nuclear receptors)-usually for steroid hormones, such as testosterone.

Hormone binding to the receptor leads to the signal cascade within the cell, which results in cell response.

The aldosterone mineralocorticoid receptors are nuclear receptors mostly located in the kidneys.
