Homework Answers
Antigen: Toxin or foreign substances which induces an immune response.
Antibody: Large proteins used by immune system to neutralize antigen.
What does Antibodies made of?
Structurally they are Y shaped and consist of 4 polypeptide chains including two heavy and two light chains.
Each part of antibody has specific function in Antibody-Antigen interaction.
Fab, as the name sugests Fragment, antigen binding, plays role in specific binding of antigen with antibody.
Fc(Fragment crystallizable region) region present at the base of the antibody plays role in mediating immune response. Fc region mediates the appropriate immune response for each antigens. This is due to the binding of Fc region to a specific Fc receptors in various cells of immune system thus producing a immune response.
Hence the answer for the question is
b).Fc

Alpaca Conventional antibody Alpaca heavy- chain antibody Nanobody/ VH CH1 VH Single domain antibodies are a type of antibody produced naturally by llamas and other camelids, which consist of only a single monomeric heavy chain or light chain but nonetheless can achieve equal binding affinity to antigens as conventional antibodies. A new product, called nanobodies, can be derived from single domain antibodies as depicted in the diagram. While their purpose in these animals is currently unclear, there is large commercial...
