Vedclass · Answer

(A) The process of urine formation involves three main steps: glomerular filtration,reabsorption,and tubular secretion.Tubular secretion is the process where cells of the renal tubule extract substances from the peritubular capillaries and secrete them into the filtrate.$K^+$ (Potassium ions),$H^+$ (Hydrogen ions),and ammonia are actively secreted into the filtrate by the tubular cells to maintain the ionic and acid-base balance of body fluids.Amino acids and sodium ions are primarily reabsorbed from the filtrate,while chloride ions follow sodium passively.Therefore,potassium ions are the substances actively secreted.

Column-$I$	Column-$II$
$a. PCT$	$i. \text{Selective secretion of } H^+ \text{ and } K^+ \text{ ions}$
$b. DCT$	$ii. 70-80\% \text{ of electrolytes and water reabsorption}$
$c. \text{Descending limb}$	$iii. \text{Allows passage of small amounts of urea}$
$d. \text{Ascending limb}$	$iv. \text{Permeable to water}$
$e. \text{Collecting duct}$	$v. \text{Permeable to salts}$

Which one of the following substances is actively secreted into the glomerular filtrate of the kidney tubule?
