Q. I. Reabsorption of water occurs passively in the initial segment of nephron II. Nitrogenous waste are absorbed by active transport III. Conditional reabsorption of $Na^{+}$ and water takes place in DCT IV. DCT reabsorbs glucose V. DCT is capable of selective secretion of $H^{+},\ K^{+}$ and $NH_{3}$ to maintain pH and $Na^{+} - K^{+}$ balance in blood VI. Substances like glucose, amino acids, $Na^{+},$ etc, in the filtrate are reabsorbed actively Choose the option with incorrect statements
A) I and II
B) III and IV
C) V and VI
D) II and IV
Explanation
DCT reabsorbs $\rightarrow Na^{+},\ K^{+},\ HCO_{3},\ NH_{3}$ and water. Nitrogenous water are absorbed by passive transport. Reabsorption of water also occurs passively in the initial segment of nephron
