What structural modification of certain tubule cells in the kidenys enhances their ability to reabsorb substances from the filtrate?

The walls of the tubules of the nephrons (the functional unit) of the kidneys are made of a single layer of transport epithelial cells. They have many special channels, pumps and transporters to retrieve the materials in the filtrate that the body doesn't want to lose. For example, in the proximal convoluted tubule, the cells have a sodium/glucose co-transporter. It uses an already existing concentration gradient of sodium to move glucose back into the cell against its concentration gradient.

I'm worried over your current state of boredom and what it could lead to with a mind like yours - Had I the time to watch canned ham expand I would surely get the weed burner out of the shed to honor you and your gelatinous thinking. but alas... no, I have not - so screw it.. I don't have the slightest idea and you can sue me for my lack of imagination when we're old. the end.
