Vesicular Transport Flashcards
What are the steps if vesicular transport
Movement by cytoskeliton and motor proteins
Tethering vesicle to target compartment via Rabs and tethering proteins
Docking of vesicle
Fusion of vesicle to target membrane
Function of smooth er
Production of steroid hormones
Detoxification
Sequestration
Functions of rough er
Protein synthesis
Sythesis of membrane phospholipids
Glycosylation of proteins
Protein folding
What are transport vesicles how
Transport of material between compartments
Uses cytoskeleton and motor proteins
Sorting signals recognized by receptors
What is the structure of the golgi complex
Smooth
~8 or fewer cisternae
Curved
Shows polarity
What does the cis golgi network
Acts as a sorting station wether proteins should continue on to tye next golgi station or back to the er
What does the trans golgi network
Sort proteins into different types of vesicles besicles go to plasma membrane or other intracellular destinations
Functions of golgi
Processing plant pf cell
Modification of proteins and lipids
Transport and sorting of proteins
How do copI and copII proteins help form vesicle and selects cargo
Assemble on cytosolic surface of donor membranes at sites where budding takes place
Which direction do COPI proteins move
Retrograde direction
COPII move in what direction
Anterograde
What lysosome function
Autophagy by fusing with ER derived autophagic vacuole formung a autolysosome
Degradation of internalized material
What is a tonoplast
Vaculolar membrane
Contains active transport system that generate high interior
Function of vacuole
Intracellular digestion
Storage
Mechanical support and turgor pressure
