6.2 Golgi Apparatus Flashcards
golgi apparatus
center of manufacturing, sorting, shipping
-prducts of the ER (proteins and stuff) are modified and stored and then sent to other destinations
golgi cells
specialized for secretion
golgi structure
lots of stacked flattened membranous sacs
cisternae
the 2 poles of a golgi stack
cis and trans face
receiving and shipping
cis face
located near the ER
-transport vesicles move materials from ER to the cis face in the golgi
cis to trans face
products are usually modified fro mcid to trans
(golgi enzymes modify the carbohydrate portion of glyoproteins)
then nonprotein golgi products leave from the trans face in transport vesicles until it can fuse with the plasma membrane
cisternal maturation model
shows that the golgi actually progresses from the cis tot he trans, carrying and modifying its package as kit goes
sorting
before the package is released, th golgi sorts and targets them for various parts of the cell
