Q. Regarding the buffer system in the tubular fluid, which one is TRUE? (Solved)
1. the main buffer system is H2PO4
2. the main mechanism of H+ secretion in the proximal tubule is via proton pump
3. dibasic phosphate buffer is most effective at proximal convoluted tubule
4. the H+ secretion at proximal tubule is mediated Na/K/ATPase
5. thick ascending limb of loop of Henle
- d. the H+ secretion at proximal tubule is mediated Na/K/ATPase
