Vedclass · Answer

(A) In the renal tubules,reabsorption occurs through both active and passive transport.$1$. Active transport: Substances like $Na^+$,glucose $(II)$,and amino acids $(IV)$ are reabsorbed actively from the filtrate into the blood.$2$. Passive transport: Substances like nitrogenous wastes $(III)$ and water $(V)$ are reabsorbed passively along the concentration gradient.Therefore,$P$ (passive transport) includes $III$ and $V$,while $Q$ (active transport) includes $I$,$II$,and $IV$.Correct option is $A$.

Components reabsorbed by passive transport - $P$
Components reabsorbed by active transport - $Q$
$I - Na^+$,$II$ - Glucose,$III$ - Nitrogenous wastes,$IV$ - Amino acids,$V$ - Water
Select the correct option for $P$ and $Q$.
$P \quad \quad Q$
