  • 3rd side (hint)
cell membrane
border of cell that gives a cell its identity and contains most activity.
maintains homeostasis
phospholipids
head with two tails
phosphuras and fat
polar head
attracts water and bonds with it on the outisde and inside wal of the cell membrane
polar bear
nonpolar tails
repel water pushed towards center of cell membrain
non polar interior zone
lipid bilayer
two layers of phospholipids form by pushing and pulling of polar heads and non tails due to their reaction wtih water
basic structure of cell membrane 2 layers
cell surface proteins
proteins that penetrate lipid bilayer providing passageways for substances to enter and leave the cell.
glucose enters
channel proteins
"gates to the cell" transports food in and wastes out
gates
receptor proteins
the informers of cell that gather information about cells surroundings. This is where hormones act.
recieve
marker proteins
id tags of cell that identify themselves from other cells inside and outside of the body
id tags
passive transport
movement of substance across cell membrane with no enery high to low concentration
downhill
diffusion
movement of particles from high to low concentration until equilibrium reached
osmosis
diffusion of water across cell membrane from high to low concentration until isotonic envirnment is reached
facilitated diffusion
movement of high and low conentration but now using proteins channels unlike other two that can pass right through the lipids
glucose
active transport
movement low to high requires enery from cell because its going towards higher concentration.
uphill battle
endocytosis is a type of what transport
active
endocytosis
process where food molecules too big to enter through protenin channels engulf into cell by vesticles
q
2 types of endocytosis are
pino and phago
pinocytosis
intake of liquid molecules into cell using vesticles in cell membrane
pina colada
phagocytosis
process where organic matter like toher cells are brough to cell and devowered
white blood cells destroying bacteria
exocytosis
dumping of matterials outside the cell
