cytosol and organelles
what cytoplasm contains
plasma membrane
1
central dogma
DNA to RNA to protein
step one
nucleus stores DNA, making RNA copies and RNA moves to cytoplasm
step two
RNA read by ribosomes and makes protein
step three
golgi body modifies the protein and gives it a location to go to in the body
vesicles
storage for proteins that arent needed yet
lysosomes
break down protein into raw materials
where DNA is stored
Nucleus
what covers nucleus
nuclear membrane
nucleus
makes RNA copies
ribosomes
reads RNA and makes proteins
golgi body
modifies proteins and gives it a location to go to
peroxisome
removes toxins from cell
smooth endoplasmic reticulum
makes lipids (fat)
mitochondria
makes ATP
centriole
makes microtubules
microtubules
pathway for organelles
microtubules
3
microfilament
gives cell its shape
microfilament
1
intermediate filament
has an anchoring point
intermediate filament
2
cilia
made of microtubules
phosphate head
hydrophilic
fatty tails
hydrophobic
phosphate head
a
peripheral proteins
messengers and anchoring points
integral proteins
acts as tunnel to let polar molecules pass
presence of glycocalyx molecules
help identify a cells self so it doesnt attack itself
glycocalyx
carbohydrate
cholestrol
keeps plasma membrane flexible
gradient
difference in concentration
passive transport
any movement in and out of the cell that doesnt require energy
simple diffusion
when O2 is higher in concentration on outside, it moves inward, passing the phospholipid bilayer, lowering the concentration outside
facilitated diffusion
needs channel protein to allow for polar molecules to pass through phospholipid bilayer
integrated protein+facilitated diffusion=
channel protein
osmosis
movement of water
low H2O=
more stuff
more H2O=
less stuff
carrier mediated active transport
integral protein takes ATP energy to move concentration from low to high
phagocytosis
bringing in solids
pinocytosis
bringing in liquids
tight junctions
creates seal between cells
desmosomes
prevents cells from ripping; helps cells move as a unit
gap junctions
molecules can pass from one cell to the next; quick communication
