Resource summary
AP Bio Unit 3: Cells
prokaryotic vs eukaryotic cell structures
what types of cells are eukaryotic and which are prokaryotic?
prokaryotic: bacteria
eukaryotic: everything else
both: genetic material
prokaryotic
eukaryotic
why are cells so small?
SA/V
more surface area means more contact with outside:
material can travel through the same "amount of cell" more easily (so no cell death)
LAD
function/structure of each organelle
how do RER, Golgi apparatus and cell membrane work to create proteins for secretion or to be used in other organelles?
How do the products of bound vs. free ribosomes differ?
1. cytoskeleton
Annotations:
like a bridge, holds up the cell and its organelles...
microtubuloes
Annotations:
the large ones??
microfilaments
2. endomembrane system
3.
Autogenous and Endosymbiotic Hypothesis
Annotations:
something abt cell origin story....
plant vs animal cells
mitochondria and chloroplasts**
circular DNA
reproduction by binary fission
generate ATP
small ribosomes
double membrane
...
gap junctions
plasmodesmata
tight junctions
desosomes
structure of phospholipid bilayer
what factors affect the permeability of a phospholipid bilayer?
role of cholesterol in animal cell membranes
transport across a cell membrane
what can pass through a cell membrane?
small, chargless compounds
contransport
exocytosis
endocytosis
passive transport
diffusion
osmosis
Annotations:
diffusion of water
facilitated diffusion
active transport
ex: pumps
types of solutions
isotonic
plant cell reaction
animal cell reaction
protist reaction
hypertonic
plant cell reaction
animal cell reaction
protist reaction
hypotonic
plant cell reaction
animal cell reaction
protist reaction
G-protein receptors
gated ion channel receptors.
signal cascades
Annotations:
occur for protein based receptors
phosphorylation cascades
epinephrine pathway
evolution of cell signaling
quorum sensing
how bacteria communicate
they are actually a multii-cellular organism
cell signaling
types of signals
protein based
hydrophilic: cannot pass through lipid bylayer
Annotations:
so bind through
bind to transmembrane receptors
lipid based
