1the complement has three main outcomes:
1. [blank_start]inflammation[blank_end]
2. [blank_start]phagocytosis[blank_end]
3. [blank_start]Membrane Attack Complex[blank_end]- Ainflammation
- Bphagocytosis
- CMembrane Attack Complex
2complement proteins are produced by the [blank_start]liver[blank_end]
- Aliver
3coplement proteins circulate in the blood in their active form
- ATrue
- BFalse
4complement pathways include the [blank_start]classical[blank_end] pathway, [blank_start]alternative[blank_end] pathway and [blank_start]lectin[blank_end] pathway.
- Aclassical
- Balternative
- Clectin
5the complement cascade functions to convert [blank_start]C3[blank_end] into [blank_start]C3a[blank_end] and [blank_start]C3b[blank_end]
- AC3
- BC3a
- CC3b
6complement proteins [blank_start]C5a[blank_end] and [blank_start]C3a[blank_end] [blank_start]enhance inflammation[blank_end] by recruitment and activation of leukocytes.
- Aenhance inflammation
- BC3a
- CC5a
7complement protein C3b has a role in [blank_start]opsonisation[blank_end] and [blank_start]formation of the MAC[blank_end].
- Aopsonisation
- Bformation of the MAC
8in the MAC the complement protein [blank_start]C5b[blank_end] acts as an anchor point for a single molecule composed of other proteins that forms a tube inserted into the [blank_start]lipid bilayer[blank_end] of the cell and causes [blank_start]lysis[blank_end].
- AC5b
- Blipid bilayer
- Clysis
9if there is no C3 the body is more susceptible to some bacterial infections but is NOT severely immunodeficient whereas if there is no MAC there is a problem because of increased bacterial susceptibility due to the lack of opsonisation and lack of formation of anapylatoxins.
- ATrue
- BFalse
10the 3 pathways for complement are as follows:
1. classical: [blank_start]binding C1 to Ab-Ag complexes[blank_end]
2. alternative pathway: [blank_start]binding of endotoxin or LPS[blank_end]
3. lectin pathway: [blank_start]mannose-binding lectin[blank_end]- Abinding C1 to Ab-Ag complexes
- Bbinding of endotoxin or LPS
- Cmannose-binding lectin
11the clotting system is divided into two converging pathways resulting in the activation of [blank_start]thrombin[blank_end] and the formation of [blank_start]fibrin[blank_end].
- Athrombin
- Bfibrin
12kinins are [blank_start]vasoactive peptides[blank_end]
- Avasoactive peptides
13kinins are derived from plasma proteins called [blank_start]kininogens[blank_end] via the action of proteases called [blank_start]kallikreins[blank_end]
- Akininogens
- Bkallikreins
14Kallikrein is activated by [blank_start]Hageman factor[blank_end]
- AHageman factor
15bradykinin is mostly responsible for increased [blank_start]vascular permeability[blank_end] and [blank_start]pain[blank_end].
- Avascular permeability
- Bpain
