Which of the following statements about aldosterone is NOT correct?

A. Aldosterone increases the number of passive sodium channels in the luminal membrane of the distal tubule and collecting duct, thus aiding sodium reabsorption.

B. Aldosterone is produced in the adrenal cortex.

C. Aldosterone increases sodium reabsorption by increasing the number of Na+-K + ATPase pumps in the luminal membrane of the proximal tubule.

D. Aldosterone is stimulated by decreased plasma sodium levels and increased plasma potassium levels.

C. Aldosterone increases sodium reabsorption by increasing the number of Na+-K + ATPase pumps in the luminal membrane of the proximal tubule.

Explanation:

Aldosterone hormone is produced by the adrenal gland and mainly carries out its functions in the kidney. Through the aldosterone hormone the body is able to retain more water for the kidney is able to hold more sodium. When the plasma sodium levels decrease and the plasma potassium levels increase the production of aldosterone hormone is stimulated for sodium is needed in the. body to maintain the high water levels in the body.
