Question

The steroid hormone aldosterone affects only a small number of cells in the body because ________. A. only target cells are exposed to aldosterone B. only target cells contain aldosterone receptors C. aldosterone is unable to enter nontarget cells D. nontarget cells destroy aldosterone before it can produce any effect

Answer 1

The steroid hormone aldosterone affects only a small number of cells in the body because nontarget cells destroy aldosterone before it can produce any effect.

Hence, option D is the correct answer.

What is Steroid hormones ?

Steroid hormones can easily pass through cell membranes. Cells have an enzyme called hydrolase that cleaves the side chains of aldosterone into small pieces and renders it non functional. Only the target cells possess intracellular receptors which helps it to travel through the nuclear membrane before hydrolase can act on it.

All cells are exposed to aldosterone. However it can function only in the cells containing the intracellular receptors.

Target cells do not contain any extra cellular receptors for aldosterone.

Aldosterone can enter all cells. It can easily pass through the lipid bilayer.

Thus from the above conclusion we can say that The steroid hormone aldosterone affects only a small number of cells in the body because nontarget cells destroy aldosterone before it can produce any effect

Hence, option D is the correct answer.
