4. Glycoproteins
Term
Phospholipids (1 of the components of the cell membrane) (2)
Definition
permeability, aracodonic acid (make icosinoids)
Term
Cholesterol (1 of the 4 components of the cell membrane) (2)
Definition
stabilizes the phospholipids, permeability
Term
Proteins (1 of the 4 components of the cell membrane) (2)
Definition
transporters, receptors

Glycoproteins ( 1 of the 4 components of the cell membrane) (2)
Definition
identification of self, hysto-typic adhesion
Term
All Endoplasmic Reticulum (all E.R.) (2)
Definition
communication and transportation in cell
Term
Rough E.R. (3)

ribosomes are attached
secretory proteins
hydrolitic enzymes for lysosomes
Term
Smooth E.R. (2)
Definition
detoxification
lipid interconversions
Term
Golgi Bodies (3)
Definition
Series of flattened membrane sacs
has both a receiving face and a discharge face
produce buds & lysosomes
Term
Ribosomes (3)
Definition
translate proteins
free or bound
in both eukaryotic& prokaryotic
Term
Mitochondria (4)
Definition
"Powerhouse"
double membrane
1 chromosome
All oxygen
Term
Secretory Vessicle (2)
Definition
exocytosis (secretion)
they secrete hydrolytic enzymes which are lysosome
Term
Plastids (5)
Definition
in plants
photosynthesis
double membrane
stroma
grana

actin (a protein that contracts)
they make up microfilaments
these are like the muscles if the cell
