Potassium is maximally absorbed in which part of nephron?

POTASSIUM: REABSORPTION AND SECRETION •  K+ is the only electrolyte that is reabsorbed as well as secreted. •  65% of the K+ is reabsorbed in PCT, 25% in loop and <10% reaches the distal nephron. •  Active reabsorption in PCT; secreted in DCT (Maximum  secretion).  K+ secretion is decreased when the amount of Na+ reaching the DCT is small. •  K+ secretion is also decreased when the H+ secretion is increased. •  In DCT, Na+ is reabsorbed and K+ and H+ compete for their secretion for the amount of Na +  reabsorbed. •  For K+ and H+ , remember  the  terms  ‘hypokalemic alkalosis and hyperkalemic acidosis’
