Question	Answer	Link
To which ion is most transport in the proximal tubule linked?	Sodium	Link
Which transporter found in the basolateral membrane is essential to maintain low intracellular sodium levels?	Sodium/potassium ATPase	Link
Why does the concentration of the tubular fluid remain constant along the tubule despite the reabsorption of ions such as sodium?	Water passively follows the reabsorbed sodium so the concentration remains fairly similar but the volume is reduced	Link
