It is also important to note that water reabsorption is heavily driven by the movement of Na+ – as a rule of thumb, water tends to follow the direction that sodium moves in. Figure 1.

Splet25. mar. 2024 · The difference between the PCT and type A intercalated cells, is that these cells can actively secrete H + into the lumen against a large concentration gradient, allowing for H + secretion in response to acidosis. Once in the lumen of the tubule, the hydrogen ions react with either phosphate (HPO 42-) or ammonia (NH 3 ).

SpletThis Editorial Review describes the mechanisms that have been identified for mediating active H+ secretion across the luminal membrane of the proximal tubular cell. These include Na+-H+ exchange, Na+-phosphate cotransport, organic anion-OH- exchange, ATP-driven H+ transport, and redox-driven H+ transport. Of these, Na+-H+ exchange appears … map of lapland sweden
