WebThe HCO 3- crosses the basolateral membrane via a Na + -HCO 3- symporter. This symporter is electrogenic as it transfers three HCO 3- for every one Na +. In comparison, the Na + -H + antiporter in the apical membrane is not electrogenic because an equal amount of charge is transferred in both directions. WebOct 18, 2024 · This process is coupled to Na + reabsorption primarily through the actions of two transporters, Na + /H + exchanger 3 (NHE3) on the apical membrane and electrogenic sodium bicarbonate cotransporter 1-A (NBCe1-A; SLC4A4) on the basolateral membrane ( … black soft hairWebJuxtamedullary Nephron: part in cortex, ...

In interstitial fluid of the kidney an increasing osmolarity from cortex to the inner medulla. This gradient is mainly caused by : WebThese mechanisms are essentially based on H-ion transport along the whole nephron. In proximal tubule cells, approximately 80% of H-ion secretion is mediated by Na+/H+ exchange, and 20% by H(+)-ATPase. In the distal nephron, acid-base transport mechanisms are located mainly in intercalated cells.
