-
3 major cell parts
cell, cytoplasm, nucleus
-
functions of cell membrane
encloses cell, site of metabolic reactions, selectivly permiable
-
selectivly permiable allows what to liquids to pass
molecules souluable in lipids(fat), not water soulable molecules
-
cell membrane composed of
lipids and protiens
-
what makes up interior cell membrane
phosphipid bilayer
-
what does phospholipid bilayer cinsist of
double layer of phospholipid molecules, hydrophilic endsand hydrophobic tails
-
2 types of cell membrane protiens
integral and peripheral
-
where are integral protiens found
inside entire cell
-
2 types of integral protiens
globular and fibrous
-
what do gobular integral protiens do
serve as channel for transport
-
what do fibrous integral protiens do
serve as receptors
-
where are peripheral protiens found
inner and outer cell membrane
-
what is the function of peripheral integral protiens
enzymes, marker molecules, allow immune system to distinguish btwn self and foreign cells
-
what is cytoplasm
material outside of nucleous
-
what is the function of cytoplasm
where food is received, processed, and used, also site for cellular activity(metabolism)
