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?

- 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

- DIncreased Flp expression
- ESoluble fas to causes apoptosis in t-cells
- FLarge amounts of Fas ligand produced to kill t-cells
