Vedclass · Answer

(A) Aldosterone is a steroid hormone (mineralocorticoid) secreted by the adrenal cortex.It plays a crucial role in maintaining electrolyte balance,specifically sodium $(Na^+)$ and potassium $(K^+)$ ions in mammals.It acts on the distal convoluted tubules and collecting ducts of the nephron to promote the reabsorption of sodium ions and water,while simultaneously promoting the excretion of potassium ions.This process increases the sodium ion concentration in the extracellular fluid $(ECF)$ and blood,thereby regulating blood pressure and blood volume.Therefore,both the Assertion and the Reason are correct,and the Reason provides a correct explanation for the Assertion.

Assertion : Aldosterone is a steroid hormone and is important in the control of sodium and potassium ion concentration in mammals.
Reason : It upgrades sodium ion concentration in the $ECF$ by promoting reabsorption of sodium ions from renal tubules and excretion of potassium ions in urine.
