Flashcards in Lec 8 Membranes Deck (43):
1

the cell as well as blank has a cell membrane

organelles

2

outer membrane of blank is continuous with RER

nucleus

3

RER is the site of blank

translation

4

cis face is the same as the blank face of golgi

forming

5

trans face is same as blank face of golgi

maturing

6

inner membrane contains

ETC

7

matrix of mitochondria is where most of the blank enzymes reside

TCA

8

invaginations of inner membrane of mitochondria

cristae

9

pH of lysosomes is

5

10

lysosomes are critical in secretion of blank

thyroid hormones

11

lysosomal metabolism storage disease

tay sachs

12

everything inside membrane and outside organelles

cytosol

13

cytosol is the site of blank

glycolysis/fatty acid synthesis

14

membranes are non covalent and blank

asymmetric

15

most phospholipids are derived from

phosphatidic acid

16

phosphatidic acid is found in blank cell types

most

17

plasmologens are found in blank cell systems

nervous, immune, cardiovascular

18

structure of myelin sheath

sphinogmyelin

19

sphingosine and fatty acid via amide linkage makes up a blank

ceramid

20

sphingomyelin, ceramide, phosphatidic acid, plasmologens all have blank

two fatty acid tails + polar head

21

hydrophobic and hydrophilic means blank

amphipathic

22

plasma membranes in water are subject to the blank

hydrophobic effect

23

phospholipid bilayers form blank, and are flexible

spontaneously

24

cell membranes are impermeable to blank molecules

polar

25

membrane fluidity influences these two things

transport, protein funciton

26

saturated fatty acid has blank carbon double bonds

no

27

unsaturated fatty acids have blank carbon double bonds

at least one

28

blank configuration of fatty acid will prevent close packing

cis

29

membrane fluidity is blank under cooler conditions

more fluid

30

membranes are blank fluid with more cholesterol

less

31

low cholesterol means blank membrane so it is easier to insert blank

thin, proteins

32

cannot remove blank proteins without destroying membrane

integral

33

blank proteins can easily be removed from membrane without destroying it

peripheral

34

post translational modification where membrane protein is covalently attached to a lipid in the membrane

lipid anchored

35

lipid anchored protein does not interact with the membrane blank

directly

36

blank must be stripped to get polar molecule across membrane

water shell

37

blank proteins help get glucose through membrane

facilitator

38

glucose transport in most cells is blank

uniport in

39

sodium and glucose co transport in the gut

symport in

40

chlorine and HCO3 in red cell membranes to get atp and adp across membranes is blank

antiport

41

once in the cell, glucose undergoes blank to make it remain in the cell

phosphorylation

42

transport proteins resemble enzymes because they blank

speed up a process, get saturated, are specific

43

membranes are blank active

surface
