Lecture 15 Endocytosis and Endosomes Flashcards
What is phagocytosis
specialized cells engulf large objects
What is pinocystosis
cellular drinking- tiny vesicles bringing in fluid
What is caveolin
it is similar to a coat protein and is associated with lipid rafts
What is transcytosis
transport vesicle through the cell
What is receptor-mediated endorcytosis
major type of endocytosis that is clathrin mediated
what is clathrin
A coat protein
What is AP?
links clathrin to membrane
What is dynamin
A large GTPase that is required to do fission during endocytosis
Where does most of the cargo sorted to
The late endosome
Proteins that need to go back to the plasma membrane use what?
Recycling vesicles
What experiment can be used to observe endocystosis
pulse-chase
Going from the Gogi to the Lysosome starts with what
Going from the golgi to the late endosome
requires clatherin, but different AP’s than endocytosis
When the protein arrives at the late endosome, where does it then go
To the MVB
but of course!!
Then when the late MVB within the late endosome wants to get rid of the annoying step-mom of a protein, where does it then go
To the lysosome so that evil witch can be degraded
What are acid hydrolases
proteosomes that function at low pH
