- how do u transport fluids, large particles, and macromolecules into the cell?
- vesicular transport
- what is vesicular trafficking?
- moving stuff from one area in the cell to another
- when u move stuff inside of a cell, how is it done?
- with vesicles
- How is vesicular transport energized?
- with ATP
- what kind of things are moved out of the cell by exocytosis
- mucous, hormones, neurotransmitters, wastes
- for exocytosis what must be first done
- enclose stuff that will be thrown out with a vesicle
- what molecules aid the process of exocytosis
- v and t snares, causes the vesicle to fuse to the plasma membrane
- what is transocytosis
- moving stuff into, across, and then out of the cell
- the vesicles that do transcytosis, vesicular trafficking, and endocytosis are coated with
- protein
- clathrin coated vesicles are used for
- endocytosis and transcytosis
- whats the first step of clathrin endocytosis
- formation of clathrin coated pit
- after the clathrin coated vesicle makes its way to the plasma membrane what happens
- it loses its clathrin
- a vesicle that just lost its clathrin coating then proceeds to fuse with another vesicle called an
- endosome
- after fusing with an endosome what happens
- a lysosome digests its contents
- what are the three types of endocytosis that use clathrin coated vesicle
- phagoyctosis, pinocytosis, and receptor mediated endocytosis
- whats the difference bt endocytosis and phagocytosis
- phagocytosis is a type of endocytosis where a large clump of solid material, like a cell or bacteria is eaten
- in phagocytosis do you use clathrin coated stuff
- yes
- whats diff about your typical endocytosis and phagocytosis
- pseudopods form in endocytosis, phag ingesting a solid particle
- whats the name of the endocytic vesicle that forms when a cell is undergoing phagocytosis
- phagosome
- who are the experts of phagocytosis
- white blood cells, and macrophages
- how do phagocytes move
- ameboid motion
- is pinocytosis endocytosis
- yes
- what kind of endocytosis do cells do to sample extracellular fluid
- pinocytosis
- is pinocytosis a routine activity done by the cell
- yes, more so than phagocytosis
- another name for pinocytosis
- fluid-phase endocytosis
- most macromolecules enter by
- receptor mediated endocytosis and transocytosis
- is receptor mediated endoctyosis very selective
- yes
- what other kind of protein coat can be used for endocytosis
- caveolae
- what is caveolae made of
- cavolin
- what is the diff bt caveolae protein capsules and those of clathrin
- caveloae make smaller vesicles and thinner ones
- these proteins line the vesicles that will be used for exocytosis
- snares
