|
proteins and phospholipids synthesized where
|
Rough ER are transported to the Golgi complex and then to secretory vesicles destined to fuse with the cell membrane via exocytosis
|
|
|
|
endosomes
|
membrane taken into the cell in fthe form of endocytic vesicles is incorporated into early endosomes which are sorting compartments concentrated at the cell's periphery
|
|
|
|
nuclear envelope
|
portion of rough ER which surounds chromosomal DNA; interrupted by nuclear pores which are hydrophilic channels through which proteins and RNA are exchanged between the cytoplasm and the nuclear cytoplasm
|
|
|
|
mitochondria
|
generate ATP
|
|
|
|
peroxisomes
|
engage in detoxification through peroxidation reactions and prevent the accumulation of the strong oxidizing agent hydrogen peroxide
|
|
|
|
smooth ER
|
functions as a regulated calcium store and also involved in lipid metabolism
|
|
|
|
microtubules
|
largest diamter fibers 25 nm; extend the full length of the neuron and form long scaffolds
|
are constrcted of 13 protofilaments in a tubular array each protofilament consists of several pairs of alpha and beta tubulin subunits `
|
|
|
tubulin
|
is a GTPase
|
|
|
|
how do microtubules grow
|
by the addition of GTP-bound tubulin dimers at their plus end
|
|
|
|
MAPs
|
microtubule associated proteins; MAP2 is present in dendrites but not axons
|
promote the oriented polymerization and assembly of the microtubules
|
|
|
neurofilaments
|
10nm in diameter are the most abundant fibrillar components of the axon; they are very stable and amost totally polymerized
|
|
|
|
chaperones
|
proteins that bind to unstructured exposed regions of the newly synthesized polypeptide
|
