1Morphological Features of Apoptosis:
1. Cell [blank_start]shrinks[blank_end]
2. The chromatins [blank_start]condense[blank_end] and [blank_start]fragmentation[blank_end] of intracellular contents occurs
3. [blank_start]Blebbing[blank_end] of membrane
4. Formation of [blank_start]apoptotic bodies[blank_end]
4. [blank_start]Phagocytic ingestion[blank_end] of ABs and degradation- Ashrinks
- Bcondense
- Cfragmentation
- DBlebbing
- Eapoptotic bodies
- FPhagocytic ingestion
2What is the key signal for engulfing?
- Acaspases
- Bphosphotidylserine (PS)
- Capoptotic bodies
3What 2 molecules prevent apoptosis?
- ABAX
- BBCL-2
- CBAD
- DBCL-X
- EBAK
4What mechanism of intracellular communication acts of distant cells?
- AParacrine
- BAutocrine
- CEndocrine
- DJuxta crime
5Phosphorylation of a protein causes it to be ACTIVE
- ARichtig
- BFalsch
6Phosphorylation occurs through using phosphatases
- ARichtig
- BFalsch
73 Ways to Terminate a signal:
1. Eliminate extracellular [blank_start]ligand[blank_end] ([blank_start]enzymatic degradation[blank_end])
2. [blank_start]Deactivate[blank_end] signal transduction proteins ([blank_start]dephosphorylation[blank_end])
3. [blank_start]Remove[blank_end] activated receptor via [blank_start]endocytosis[blank_end]- Aligand
- Benzymatic degradation
- CDeactivate
- Ddephosphorylation
- ERemove
- Fendocytosis
8What are extracellular signals?
- Ahormones
- Bprotein kinases
- Ccytokines
- Dgrowth factors
- Elipids
- Fcarbohydrate
93 Effector Molecules:
1. [blank_start]Adenylyl[blank_end] cyclase
2. [blank_start]Phospholipase[blank_end] C
3. [blank_start]PI3-[blank_end]Kinase- AAdenylyl
- BPhospholipase
- CPI3-
10In terms of second messengers, cAMP is paired with protein kinase G and cGMP is paired with protein kinase A.
- ARichtig
- BFalsch
11How is cAMP produced:
[blank_start]Adenylyl Cyclase[blank_end] -> converts [blank_start]ATP[blank_end] to cAMP.
What does cAMP stimulate?
cAMP -> binds to [blank_start]PKA[blank_end] ([blank_start]regulatory[blank_end] domains) -> dissociation of [blank_start]catalytic domains[blank_end] -> [blank_start]C[blank_end] domains can bind and activate other proteins- AAdenylyl Cyclase
- BATP
- CPKA
- Dregulatory
- Ecatalytic domains
- FC
12What enzyme catalyses the action of converting PIP2 to PIP3?
- APTEN
- BPhospholipase C
- CPI-3 Kinase
13What can PIP2 be split into?
- ACa2+ and IP3
- BDAG and IP3
- CPKB and PKC
14Phospholipase C splits PIP2 into 2 different molecules.
- ARichtig
- BFalsch
15DAG -> [blank_start]PKC[blank_end]
IP3 -> [blank_start]Ca2+[blank_end]- APKC
- BCa2+
