BIO 205 Quiz 5 Questions and answers with accurate rationales(PASSED).
first line of defense - (ANSWER)External Physical Barriers - Skin and mucous membranes
Made up of structures, chemicals, and processes that work to prevent pathogens entering the body.
Includes the skin and mucous membranes of the respiratory, digestive, urinary, and reproductive
systems.
4 cardinal signs of inflammation (plus bonus sign) - (ANSWER)Heat, Pain, Redness, Swelling AND loss of
function sometimes
Smoking and many analgesic drugs (painkillers) leads to an increased risk of infection of the respiratory
and digestive tract. Why? - (ANSWER)Smoking impairs the ciliated cells of the respiratory tract.
Analgesic drugs impair peristalsis(the churning motion of the digestive tract). This leads to an increased
risk of infection in their respective areas.
Pyrogens - (ANSWER)fever-inducing substances
Plasma cells - (ANSWER)plasma cell secretes Ab's. Ab's circulate through the body, attacking antigenic
determinants. (a fully differentiated B cell that produces a single type of antibody)
Memory cells - (ANSWER)Some B cells form long-lived memory B cells which respond quickly if antigen
encountered again
Antigens - (ANSWER)Antigen comes from ANTIbody GENerator.
Describes a molecule that reacts specifically with antibody, a B-cell receptor, or a T-cell receptor
Antibodies - (ANSWER)Structure: Y shaped proteins. Monomer unit made of four chains of amino acids
held together by disulfides bonds. Two chains are heavy, Two chains are light. Each heavy and light chain
has a constant and a variable region.
Has 2 parts:
, BIO 205 Quiz 5 Questions and answers with accurate rationales(PASSED).
-Two identical arms- Fab region ( antigen binding)- variable region is unique to each Ab and accounts for
specificity
-The Stem- Fc region (crystallized)- Constant region- Allows immune system components to recognize
otherwise diverse antibody molecules
Immunogens - (ANSWER)Antigen that elicits/causes immune response called an ________________.
Example, normal protein from host A that elicits an immune response in host B is an antigen but is only
an immunogen for host B
Immunoglobulins - (ANSWER)any of a class of proteins present in the serum and cells of the immune
system, that function as antibodies.
Which molecules induce the strong immune response and which don't? - (ANSWER)Proteins and
polysaccharides induce strong response
Lipids and nucleic acids often do not
Which of the following do not induce a strong immune response?
1. Lipids
2. Proteins
3. Polysaccharides
4. Simple sugars.
5. Lipids and simple sugars. - (ANSWER)5. Lipids AND simple sugars.
5 classes of antibodies - (ANSWER)IgG
IgA
IgM
IgD
IgE
