Lec 8 Membranes Flashcards
the cell as well as blank has a cell membrane
organelles
outer membrane of blank is continuous with RER
nucleus
RER is the site of blank
translation
cis face is the same as the blank face of golgi
forming
trans face is same as blank face of golgi
maturing
inner membrane contains
ETC
matrix of mitochondria is where most of the blank enzymes reside
TCA
invaginations of inner membrane of mitochondria
cristae
pH of lysosomes is
5
lysosomes are critical in secretion of blank
thyroid hormones
lysosomal metabolism storage disease
tay sachs
everything inside membrane and outside organelles
cytosol
cytosol is the site of blank
glycolysis/fatty acid synthesis
membranes are non covalent and blank
asymmetric
most phospholipids are derived from
phosphatidic acid
phosphatidic acid is found in blank cell types
most
plasmologens are found in blank cell systems
nervous, immune, cardiovascular
structure of myelin sheath
sphinogmyelin
sphingosine and fatty acid via amide linkage makes up a blank
ceramid
sphingomyelin, ceramide, phosphatidic acid, plasmologens all have blank
two fatty acid tails + polar head
hydrophobic and hydrophilic means blank
amphipathic
plasma membranes in water are subject to the blank
hydrophobic effect
phospholipid bilayers form blank, and are flexible
spontaneously
cell membranes are impermeable to blank molecules
polar
membrane fluidity influences these two things
transport, protein funciton
saturated fatty acid has blank carbon double bonds
no
unsaturated fatty acids have blank carbon double bonds
at least one
blank configuration of fatty acid will prevent close packing
cis
membrane fluidity is blank under cooler conditions
more fluid
membranes are blank fluid with more cholesterol
less
low cholesterol means blank membrane so it is easier to insert blank
thin, proteins
cannot remove blank proteins without destroying membrane
integral
blank proteins can easily be removed from membrane without destroying it
peripheral
post translational modification where membrane protein is covalently attached to a lipid in the membrane
lipid anchored
lipid anchored protein does not interact with the membrane blank
directly
blank must be stripped to get polar molecule across membrane
water shell
blank proteins help get glucose through membrane
facilitator
glucose transport in most cells is blank
uniport in
sodium and glucose co transport in the gut
symport in
chlorine and HCO3 in red cell membranes to get atp and adp across membranes is blank
antiport
once in the cell, glucose undergoes blank to make it remain in the cell
phosphorylation
transport proteins resemble enzymes because they blank
speed up a process, get saturated, are specific
membranes are blank active
surface
