Question

Tubular epithelial cells of the collecting duct and distal tubule contain receptors for what hormone that stimulates sodium reabsorption?

1) antidiuretic hormone
2) renin
3) aldosterone
4) atrial natriuretic peptide
5) erythropoietin

Answer 1

Aldosterone stimulates sodium reabsorption in tubular epithelial cells of the collecting duct and distal tubule.

Step-by-step explanation:

The hormone that stimulates sodium reabsorption in tubular epithelial cells of the collecting duct and distal tubule is aldosterone. Aldosterone stimulates the uptake of sodium (Na+) on the apical cell membrane of these cells, promoting sodium reabsorption.
