1
Q
Factors influencing rigidity of membrane
A
Low temp & saturated fat - more rigid
High temp & unsaturated fat - less rigid
Cholesterol can do either
2
Q
Flipase
A
Transports from outer to inner leaflet
3
Q
Flopase
A
Moves from inner to outer membrane
4
Q

A
Nonspecific; no energy required
5
Q
What is GLUT 5 specific for?
A
Fructose
6
Q
What is GLUT 2 specific for?
A
Galactose, fructose, and glucose
7
Q
Cardiotonic drugs
A
Inhibits Na+/K+ pump, brining in more Na+ to the cell; in turn, inhibits Na+/Ca2+ exchanger
8
Q
Gastric proton pump inhibitors
A
Blocks H+ from being pumped into gastric lumen; decreases HCl
9

A
Phosphatidylcholine, shingomyelin, glycolipids
10
