Q. Regarding renal tubular function: (Solved)
1. Na+ is actively transported out of the thin portions of the loop of Henle
2. Na+ -K+ ATPase pumps Na+ out of the renal tubule
3. Cl- is transported only by co-transport
4. glucose is reabsorbed mainly in the distal tubule
5. penicillin is not actively secreted into tubular fluid
- b. Na+ -K+ ATPase pumps Na+ out of the renal tubule
