chapter 6 Flashcards
carriers
facilitated diffusion
pumps
primary active transport
receptors
receive stimulis
cholesterol
changes fluidity, can make more rigid, keeps membrane from cracking
glycolipid
protein plus lipid
hypertonic
concentrated solutes on the outside
hypotonic
dilute solutes on the outside
facilitated diffusion
ligand opens, no energy needed, used concentration (gradient), proteins helps things move through membrane
active transport
used tap, no gradient, can work against a gradient
uniporter
1 substance in 1 direction
symporter
2 substances in 1 direction
antiporter
2 substances in opposite directions
snares
exocytosis, wrap around each other creating torque and pushes stuff out
roles of the cell membrane
-can work with energy transformations
-organize enzymes-chemical reactions
-info processing
