Vedclass · Answer

(A) During pregnancy,the glomerular filtration rate $(GFR)$ increases significantly due to physiological changes in the body.Because of this increased $GFR$,the amount of glucose filtered into the renal tubules (tubular load) increases.When this load exceeds the renal threshold (tubular maximum) for glucose reabsorption,the excess glucose cannot be reabsorbed and is excreted in the urine,a condition known as glycosuria.Therefore,both the Assertion and the Reason are correct,and the Reason provides the correct explanation for the Assertion.

Column $I$ (Function)	Column $II$ (Part of Excretory System)
$(a)$ Ultrafiltration	$(i)$ Henle's loop
$(b)$ Concentration of urine	$(ii)$ Ureter
$(c)$ Transport of urine	$(iii)$ Urinary bladder
$(d)$ Storage of urine	$(iv)$ Malpighian corpuscle
	$(v)$ Proximal convoluted tubule

$A$: Pregnant women may show some presence of glucose in their post-prandial urine although they have no diabetes.
$R$: In pregnant women,the glomerular filtration rate $(GFR)$ is slightly increased. As a result,the tubular load of glucose exceeds the tubular maximum for glucose reabsorption.
