Answer 1

In most cases along the nephron, the driving force in the reabsorption of solutes is the downward concentration gradient of -ATPase, which is localized in the basolateral membrane.

Ion Transport in the Kidney Tubules

• The -ATPase, which is located in the basolateral membrane, is the main enzyme that drives Na+Cl reabsorption, according to the current review of the subject.
• As a result of the tiny ionic gradients that form in the proximal tubule, where bulk reabsorption occurs, the transport here is so cost-effective.
• As a result of Na+Cl- being reabsorbed and water being unable to follow, the TAL already has less efficient transport, but this nephron segment builds up ionic gradients (the urinary concentrating mechanism).
• However, incredibly high ionic gradients can be built up here despite the expensive transport. ADH and aldosterone are the two hormones that play the most significant roles in mediating the regulation.
