How do cells keep us healthy?
Homeostasis
proteins
transport/carrier proteins
channel proteins
receptor proteins
types of solutions
hypotonic
hypertonic
isotonic
phospholipid bilayer
phospholipids
polar (negatively charged) heads
nonpolar (neutral) tails
large molecules and charged ions cannot get through
small, nonpolar molecules can get through
endocytosis
exocytosis
viruses
use "key" to unlock "lock" of cell membrane
multiply once inside cell membrane
killed by white blood cells
Concentration gradient
High to low
simple diffusion
facilitated diffusion
active transoprt
plants vs animal cells
plant cells
extra layer of membrane called a cell wall
large vacuoles
turgor pressure
animal cells
size and charge
small and nonpolar
slip through cell membrane
carbon dioxide
large and polar
need a channel protein
glucose
water (h20)
can slip through slowly
