Flashcards in fong IV Deck (12):
what are epithelia?
polarized cell sheets separated by tight junctions
what are the transport proteins
-carriers (symporters, anitporters, etc)
what are the transport processes?
-secondary active (coupled carriers)
-passive (channels, some carriers)
what uses secondary active transport>
PT reabsorption of glucose
this pump maintains low intracellular Na+and thereby facilitates the apical uptake of glucose
basolateral glucose moves passively via
what does the PT reabsorb?
CA inhibitors inhibit what process?
PT reabsorption of HCO-/3
the proximal tubule effeciently recovers what?
-filtered amino acids
-low molecular weight proteins (LMPs)
are PTs highly water permeable?
transport in the PT is
