Antigens and Antibodies Flashcards
1
Q
What are antibodies produced by?
A
- Produced by B cells
2
Q
What essential role do antibodies play in biological activities?
A
- Play essential role in biological activities related to the immune response such as opsonization and complement activation
3
Q
What are the 5 different classes of antibodies?
A
- IgG
- IgM
- IgA
- IgD
- IgE
4
Q
What does each antibody molecule have in regards to its chains?
A
- Each antibody molecule has two identical heavy chains and two identical light chains
5
Q
What are the antibody chains joined together by?
A
- These chains are joined together by disulfide bridges
6
Q
How are different antibody classes distinguished?
A
- Different classes are distinguished by their distinctive heavy chain type.
7
Q
To be more specific, what regions on the heavy chain determine the unique antibody class function?
A
- More specifically, constant regions on the heavy chain are what determine the unique antibody class functions
8
Q
What are variable regions responsible for?
A
- Variable regions on both heavy and light chains are responsible for antigenic specificity (highly variable)
9
Q
What are the two types of light chains?
A
- Two types of light chains: kappa chains and lambda chains
10
Q
What does the hinge region provide?
A
- There is also a hinge region that provides flexibility
