,b. It can be directly activated by death receptors via DISC formation and
activation of Caspase-8
c. It is a molecular killing machine that massively activates Caspase-3
d. It is antagonized by anti-apoptotic IAP proteins - 🧠 ANSWER ✔✔b. It can
be directly activated by death receptors via DISC formation and activation
of Caspase-8
Indicate False about TNF-alpha, an inflammatory cytokine that in spite of
binding a receptor containing a dead domain does not cause apoptosis in
many cell types:
a. TNF-alpha treated cells survive because TNF-alpha can't activate the
extrinsic apoptosis pathway through DISC formation
b. TNF-alpha activation of the NFKB pathway leads to transcription of the
anti apoptotic Bcl-2 member Bcl-XL and the IAP apoptosome inhibitor.

, c. The TNF-alpha receptor activates DISC leading to caspase 8 activation
d. TNF-alpha treated cells can show cleavage of caspase 3 - 🧠 ANSWER
✔✔a. TNF-alpha treated cells survive because TNF-alpha can't activate the
extrinsic apoptosis pathway through DISC formation
Indicate the only mechanism unique to the extrinsic pathway of apoptosis
a. Death receptor recruitment of the adaptor FADD and caspase 8 with
formation of the DISC signaling complex
b. Mitochondrial release of Cytochrome C leading to apoptosome formation
c. Cleavage of pro caspase 3
