Cell
Transport
Osmosis
water diffusion through semi-permeable membrane
Passive
move down concentration gradient
Diffusion
high to low concentration
Active
ATP used to pump against concentration gradient
cells are charged
sodium-potassium pump cycle
Endocytosis
Phagocytosis
cell eating
Pinocytosis
cell drinking
Exocytosis
how cells release molecules
Membranes
plasma membrane
phospholipid bilayer
defines cell border
has lipid, protein channels
Chloroplasts
outer membrane
permeable to small molecules
inner
not permeable
studded w/ transport proteins
Mitochondria
inner
cristae
mitochondrial matrix
outer
surrounds
Transport Through
Factors
charge
non-polar can cross
charged can't cross
Size
ex: water is small so easy to move
stray DNA or RNA can't get in
Endoplasmic Reticulum
Smooth
protein buds out
Rough
covered in ribodomes
mRNA find ribosome
attach
protein is translated in lumen of ER
packages proteins
send them outside cell
Golgi Apparatus
vesicle attaches to golgi body
proteins mature
merge w/ membrane
transported outside the cell
transported to cell membrane in vesicles
