Which of the hormones below is responsible for facultative water reabsorption? Question options:

aldosterone

ADH

atrial natriuretic peptide

thyroxine

ADH

Explanation:

facultative water reabsorption - The water withdrawn from the plasma filtrate as a regulated negative feedback control of hydration status under the influence of ADH = antidiuretic hormone; this water reabsorption occurs primarily in the loops of the nephrons, particularly the juxtamedullary nephrons; the quantity of water reabsorbed in this fashion represents from ~1% to ~10% of the total water reabsorbed by the renal tubules.

the relative standard reduction potential of the half-cell in which reduction occurs; more positive than the other half-cell. reduction is a chemical process in which electrons are added to an atom or an ion; it always occurs accompanied by oxidation of the reducing agent.
