cells and organelles Flashcards
2 ways chromatin is packaged
euchromatin and a more dense heterochromatin
euchromatin
active genes
heterochromatin
inactive genes
exocytosis
release of secretory vesicle at plasma membrane
autophagy
lwhen ysosomes degrade obselete membrane bound organelles
how are lysosomes formed
via transport vesicles from trans- golgi fusing with late endosome
types of endocytosis
phagocytosis
pinocytosis
receptor mediated endocytosis
ubiquitin
misfolded proteins are tagged with this proteasome to be degraded
what are microfilaments for
structural shape to cells in respect to their environment
contractile forces for cell to move
what are microfilaments made of
actin and myosin
what are the two types of cholesterol and which one is better
LDL and HDL (high/low density lipoproteins)
LDL is bad for you
