selection of cargo molecules,
budding,
and fusion with the appropriate target membranes
cargo protein
Any protein that is carried within the vesicles of a cell's secretory system
which complexes fill the space between a clathrin lattice and a vesicle membrane.
AP1 complexes
AP2 complexes
AP3 complexes
GGA
degrade extracellular materials taken up by the cell and intracellular components under certain conditions.
endocycotic
through interaction of a diacidic sorting signal in the cargo protein's cytosolic domain with sec 24
Rab
clathrin/AP2-coated pits and vesicles.
COPII
protein complex that coats membrane-bound transport vesicles
copi and copii
receptor mediated endocytosis
Rough ER
sec 13 and sec 31
They revealed the order of the steps in the process.
the c terminus of the recruited protein
autophagosomes
sec 24; COPII
late endosome
v snares
apical and basolateral
lipoprotein carriers
Rab proteins
ARF
cholesterol esters
Transport of membrane and soluble proteins is mediated by transport vesicles.
Cargo proteins are collected in buds arising from the membrane of one of the compartments involved in the transport.
Delivery of cargo proteins requires membrane fusion.
As transport vesicles bud from one membrane and fuse with the next, the same face of the membrane always faces the cytosol.
All of the answers are correct.
in vesicles carrying proteins from the trans-Golgi network to the cell surface, lysosomes, and late endosomes
10-20 minutes
cis-Golgi cisterna
three clathrin heavy chains and three clathrin light chains.
multivesicular endosomes or bodies.
ER to cis-Golgi.
COPI-mediated retrograde transport
Their sheer abundance causes them to be passively loaded into COPII vesicles.
transcytosis
Only some cells exhibit ____ secretion, while all cells exhibit ___ secretion.
regulated, constitutive
The ER
furin
late endosome
blocking the packaging of CFTR in COPII vesicles.
late endosome
Sec 23/Sec24 and Sec 13/Sec31 complexes and Sec 16.
They control the docking of vesicles on target membranes.
ESCRT
proteins destined for the cell surface
proteins destined for lysosomes
vesicle components such as v-SNAREs
All of the answers are correct.
all of the answers are correct
Sar1
Place the cell structures into the correct order for the secretory protein synthesis and export from the cell
protein synthesis>protein modification > protein transport between organelles> protein modification and packaging for secretion >protein transport to plasma membrane>protein export from the cell
ribosome > rer> transport vesicle > golgi apparatus> transport vesicle > plasma membrane
What are the differences between phagocytosis and autophagy?
Only one of the processes is a type of endocytosis ()
Phagocytosis is specific to a few cell types, while autophagy is a common cellular degradation method
autophagy degrades intracellular material, while phagocytosis degrades extracellular material
