|
group of membranes and organelles working together to modify, package and transport lipids and proteins (ER, Golgi apparatus, and lysosomes.)

|
|
direction of secretory vesicles to the cell membrane either secreted to the extracellular environment or added to the PM. STEPS: budding – tethering – docking – priming (neurons) – fusion (response to calcium elevation)

|
|
cellular eating for large solid particles (bacteria or cellular debris). Particle binds to receptor leads to actin cytoskeleton rearrangements which forms a phagosome which fuses with lysosome (phagolysosome) digested

|
lipids that control the correct timing and location of trafficking events

|
|
macropinocytosis: nutrients and fluids (cellular drinking) and micropinocytosis: small molecules and membrane receptors (highly specific)
|

|
Polarity protein complexes (PAR) start learning
|
|
master regulator of polarity establishment in many cell types

|
|
molecular switches: off when GDP bound, on when GTP bound. NO PHOSPHORYLATION the guanine-nucleotide exchange factor (GEF) exchanges the GDP by a GTP to turn on, and its turned off by a GAP (liberation of a Pi)

|
|
consitutive continuous and not regulated stream of vesicles with lipids and proteins for extracellular matric or PM. Regulated for proteins that are stored and secreted on demand

Vesicle targeting and fusion V-snare (membranes of transport vesicles) and T-snare (target membrane) form the SNARE complexe when bound
