1What is the main difference between apoptosis and necrosis?
- AIn necrosis release of cell contents is controlled
In apoptosis it's not - BIn apoptosis release of cell contents is controlled
In necrosis it's not
- AIn necrosis release of cell contents is controlled
2What protein condenses during apoptosis
- AChromatin
- BActin
- CMyosin
3What form are caspases usually found in?
- AInactive, with their DED domain tails intact
- BActive, with their DED domain tails intact
- CInactive, with their DED domain tails removed
- DActive, with their DED domain tails removed
4What is required for caspase activation?
- AAddition of a DED domain tail
- BRemoval of the DED domain tail
5What are the roles of the 2 main caspases?
- A3 is the initation
8 does most damage - B8 is the initiator
3 does most damage
- A3 is the initation
6Which of the following are survival/protector proteins that inhibit caspase activation?
- ABAX, BAD, PUMA
- BBci-2, Mcl1, A1
7What is required for ligand acitvated apoptosis?
- AFor the receptors to contain DED domains
- BFor the receptors to be bound to caspases
- CFor the receptors to be expressed only in certain areas of the cell membrane
8What protein inhibits the activation of apoptic receptors?
- AFlp
- BFlr
- CFld
9Name an apoptic receptor
- AFas
- BFar
- CFam
10How does the receptor activate caspase 8?
- ABy recruiting it and cleaving off the DED domain
- BBy recruiting it and adding a DED domain
11Name the two methods caspase 8 uses to destroy the cell
- AActivation of Caspase 3
- BDeactivation of Caspase 3
- CDamage to mitochondria, which releases Cyt. C
12What does mitochondrial damage do to Casp 9?
- AActivates it
- BDeactivates it
13What happens when essential growth factors are withdrawn from the cell?
- API3K cannot activate
- BPKB cannot activate
- CCasp 8 cannot activate
14How does PKB inhibit apoptosis?
- AReleases Bad from Blc-2
- BReleases Blc2 from Bad
15Identify methods which cells can use to evade apoptosis
- ADecreased Fas receptor expression
- BInc Blc2 & decrease bax/bad expression
- CLoss of Casp 8
- DIncreased Flp expression
- ESoluble fas to causes apoptosis in t-cells
- FLarge amounts of Fas ligand produced to kill t-cells
