Question 4 1 pts How does the Nat-K ATPase's action on the peritubular side fundamentaly enable the reabsorption of the other solutes like glucose, bicarbonate, amino acids etc. coupled to

entry on the luminal side? The ATPase generates ATP, which divectly powers the luminal cotransporters moving stucose, anino acids, efc, inteo the cel. Dy maintaining a low intracehilar Nat concentration and a negative membrane potential, the ATPase creates an electrochemical gradient for Nat entry acroos the huminal membrane, and this gradient provides the energy for the secondary active transport of coupled solutes against their own gradents. The ATPase transports K into the cell, and this increased intracelular K is then exchanged for luminal glucose or amino acids by specific transporters. The active eatrusion of Nas by the ATPare creates a high concentration of Na in the peribubular space, which drives the paracelular reabsorption of glucose and amino acids.
