what are the units of k

1/sec

8

the more active enzyme means higher/lower Km

lower Km

9

holoenzyme def

apoenzyme def

holo: enzyme-cofactor complex

apo: enzyme without anything bound to it

10

where does the CD8 and CD4 bind on an MHC (describe where)

there are 4 circles
top 2 are binding sites for antigen
lower LEFT circle = binding site for CD4 or CD8

11

precursor to diaphragm - germ NAME

septum transversum

12

septum transversum is formed when cells from what germ layer invade the coelum and close it off

somatic LPM

13

this structure shunts the liver in the fetus

this structure goes from pul truck to aorta

liver-ductus venosus
pul truck-ductus arteriosus

14

disease where you have a persistent ductus arteriosus is called

persistant truncus arteriosus

15

17

AID enzyme does what
AIRE enzyme does what

AID-Affinity maturation AND class swithcing
AIRE-expresses self tissue antigens in negative selection of T cell selection

18

in B cell activation (T dep), in FIRST step, who presents antigen to who

B cell presents antigen TO T helper cells

19

name the disease where you are deficient in CD40L
what's the significance of not having CD40L

X linked Hyper IgM syndrome

you don't class switch (only have IgM)

20

FcRn R
intestinal

21

in secondary immune response, which is the most abundant Ig

most abundant = IgG

22

2 ways to enhance B cell activation (T cell INDEP)

1 B cell's CR2 R binds to C3d
