How does the complement system contribute to the innate
immune response?
a) It is composed of monocytes, including macrophages and
dendritic cells, that engulf and destroy pathogens.
b) It is composed of the phagosome and the lysosome, which
fuse to make the phagolysosome, and exposes pathogens to
digestive enzymes.
c) It is composed of proteins that can be activated by the
presence of pathogens to form the membrane attack complex
(MAC).
d) It is composed of lymphocytes that recognize and destroy cells
that are abnormal in some way. - ANSWER-C
The group of plasma proteins act as sensors for pathogens
or mediators between innate and adaptive responses. Once
activated, the complement proteins assemble into a

membrane attack complex (MAC), which polymerizes pores
in the membranes of gram-negative bacteria.
The ability of lymphocytes that recognize and destroy cells that
are abnormal in some way are a part of what immune response? -
ANSWER-Adaptive immune response
Why are antimicrobial peptides (AMPs) considered an innate
immune function?
a) AMPs are found only in mucosal membranes.
b) AMPs are agents synthesized to target and damage specific
pathogens.
c) AMPs damage pathogens by producing digestive enzymes.
d) AMPs are produced both routinely and as a response to
pathogens. - ANSWER-D
AMPs are always being produced, but they reach elevated
levels after an invasion by a pathogen. Since they are
routinely produced and are not synthesized for a specific
pathogen, they are considered an innate immune function.

Which terms refer to monocytes when they differentiate into
tissue-specific phagocytes?
a) Macrophages and dendritic cells
b) Basophils and mast cells
c) Granulocytes and lymphocytes
d) Neutrophils and eosinophils - ANSWER-A
Macrophages and dendritic cells can reside in body tissues
for significant lengths of time. Not only do they provide
immune protection for the tissue in which they reside, but
they also support normal function of neighboring tissue cells
through the production of cytokines. They are considered the
bridge between innate and adaptive immune responses.
What is specifically being reported if the Centers for Disease
Control and Prevention reports 10,000 new cases of COVID-19?
a) Incidence
b) Morbidity rate
c) Prevalence
, 4|Page
d) Mortality rate - ANSWER-A
This term refers to the number of infected people, normalized by a
selected population size - ANSWER-Morbidity rate
This term refers to the total number of infected people at any
given time - ANSWER-Prevalence
What is the difference between prevalence and incidence?
a) Prevalence refers to the total number of infections; incidence
refers only to new cases.
b) Prevalence refers to total deaths; incidence refers to
normalized deaths.
c) Prevalence refers to total deaths; incidence refers to new
deaths.
d) Prevalence is the total number of infections; incidence is
normalized by a selected population size. - ANSWER-A
