7) Considering the magnitude of glomerular filtration, theextent of tubular reabsorption is tremendous:
e.g., the tubules typically reabsorb >99% of the filteredwater (47 gallons/day), 100% of filtered sugar
(2.5 lbs/day), & ~99.5% of the filtered salt (0.65lb/day).
Describe the processes involved in passive and active reabsorption.Which membrane (i.e., which side
of the tubule cell) contains the Na + ï€K + pumps? How does thispump effect [Na + ] in the epithelial cell?
