20
Q

APO-A –

A

ligand for 2 receptors/transporters ABCA1&SRB1

21
Q

lipoprotein

A

phospholipid with apoprotein croplet containing TG and CE

22
Q

apo protein

A

stabilize droplet and have act enzyme and transporters

23
Q

chylomicron

A

made from interstinal mucosal cell

24
Q

ACAT

A

Chol-> CE in int. mucosal cell

25
Q

apo protein C and E

A

CM

26
Q

LPL

A

TG to FA in CM and transfers to adipose cels

27
Q

once in Adipose cell

A

FA made back to TG

28
Q

after CM delivers TG to adipose cell

A

it delivers CE to Liver

29
Q

CM binds to liver thru

A

APo E

30
Q

Liver make

A

TG from F CE FROM CHOL bile from Chol

31
Q

VLDL

A

come from Liver

32
Q

VLDL

A

apo B and C TG and CE

33
Q

go to adipose tissues

A

LDL and VLDL

34
Q

LPL acts in

A

LDL and VLDL to make FA and deliver to adipose tissue

35
Q

after coming from adipose tissue

A

LDL is formed from VLDL

36
Q

only hase apo B

A

LDL after adipose tissue

37
Q

endocytosis

A

of LDL particle on Peripheal cell(CE in)

38
Q

adrenal gland recieves

A

LDL and takes in CE to form Chol(make steroid hormones)

39
Q

tf all cells have ability to make cholesterol

A

T but only liver and adrenal cells do

40
Q

Liver secretes APO a

A

to another peripheal cell

41
Q

ABCA1

A

transporter for APO A

42
Q

Chol and phospholipid combined

A

with APO A1 to make HDL

43
Q

SBR1

A

on liver and recieves HDL(with chol and phospholipid)
