Flashcards in fong IV Deck (12):
1

what are epithelia?

polarized cell sheets separated by tight junctions

2

what are the transport proteins

-pumps
-carriers (symporters, anitporters, etc)
-channels

3

what are the transport processes?

-active (pumps)
-secondary active (coupled carriers)
-passive (channels, some carriers)

4

what uses secondary active transport>

PT reabsorption of glucose

5

this pump maintains low intracellular Na+and thereby facilitates the apical uptake of glucose

SGLT

6

basolateral glucose moves passively via

GLUT

7

what does the PT reabsorb?

HCO-/3

8

CA inhibitors inhibit what process?

PT reabsorption of HCO-/3

9

the proximal tubule effeciently recovers what?

-filtered amino acids
-oligopeptides
-low molecular weight proteins (LMPs)

10

are PTs highly water permeable?

yes

11

transport in the PT is

iso-osmotic

12

should there be any pressure in the bowmans capsule in health?

no
