Q. I. $Na^{+}$ II. $H_{2}O$ III. $HCO_{3}^{-}$ IV. $H^{+}$ V. $K^{+}$ VI. $NH_{3}$ Which of the given ions are reabsorbed and secreted DCT? Reabsorb Secreted
A) I, II and III IV, V and VI
B) IV, V and VI I, II and III
C) I, II and V III, IV and V
D) III, IV, and VI I, II and V
Explanation
DCT (Distal Convoluted Tubule) Conditional reabsorption of $Na^{+}$ and water takes place in this segment. DCT also capable of reabsorption of $HCO_{3}^{-}$ and selective secretion of hydrogen and potassium ions and $NH_{3}$ to maintain the pH and sodium-potassium balance in blood
