Which of the following is a characteristic of the adaptive immune system?
a .It is a specific response against microbial antigen
b. It includes inflammation.
c. It activates the alternative complement pathway.
d. It includes defenses on the body surfaces.
2. C-reactive protein is an opsonin because it:
a. creates a channel in bacterial membranes
b. increases C3b binding to a microbe.
c. forms the pathogen-associated molecular patterns.
d. enhances phagocytosis.
3. The rapid increase in antibody production after repeated exposures to the same antigen is due to:
a. antibody-dependent cellular cytotoxicity.
b. higher levels of IgE
c. presence of memory cells.
d. clonal proliferation of NK cells
4. Cytotoxic T cells can kill cancer cells by:
a. inducing apoptosis with granzyme.b. release of membrane attack complex.
c. activate the production of complement C3b
d. phagocytosis of opsonized cells.
5. Which event is not required for the activation of helper T cells?
a. The presence of interleukin-1
b. Binding of CD8 receptors
c. Binding of matching non-antigenic proteins of the antigen-presenting cel
d. Presentation of an antigen bound to class II MHC
