What are the distal and collecting tubules the site of
A)aldosterone and vasopressin action
B)the organic ion secretory systems
C)the cotransport carriers for glucose and amino acid reabsorption
D)glucose reabsorption

Question

Quizplus · Accepted Answer

Aldosterone and vasopressin directly regulate the reabsorption of Na+ and water in the distal and collecting tubules.

Answer: B 
 The organic ion secretory systems, such as the anion exchange and cation exchange systems, are located in the distal and collecting tubules.

Answer: C 
 The cotransport carriers for glucose and amino acid reabsorption are primarily located in the proximal tubules, not the distal and collecting tubules.

Answer: D 
 Glucose is primarily reabsorbed in the proximal tubules through glucose transporters. There may be some limited reabsorption of glucose in the distal and collecting tubules, but it is not the primary site of glucose reabsorption.
