Reabsoprtion of na by active transport occurs
Web5. Potassium reabsorption in the PCT is by solvent drag. 6. Secretion of toxins and organic waste products occurs in the PCT by secondary active transport. 7. Secretion of K+ occurs in the CD in response either to increased delivery of Na+ or increased fluid flow. Secretion of K + can be increased by aldosterone. 8. WebReabsorption is a highly specific process that occurs through specific proteins located on the apical membrane of kidney tubule cells. Reabsorption of substances mainly occurs through secondary active transport with Na +. This transport is made possible by the activity of the primary active transporter, the Na + /K + ATPase pump.

WebSdum reabsorption subsequently happens at four main sites in the nephron - the proximal tubule, loop of Henle, dstal tubule and collecting duct. Normally, about 99.4% of the filtered sodlum load is resorbed to maintain the con- stancy of total body sodium. The primary sites of this reabsorption are the proximal tu- bule and the loop of Henle.

Reabsorption of water in the nephron occurs by active transport. Explanation: Reabsorption of water in the nephron occurs by active transport in certain segments of the nephron, such as the thick ascending limb of the loop of Henle and the early distal tubule.
