Chapter 43, Problem 8TYU
Summary Introduction
To draw: The antibody-linking protein complex that could trigger endocytosis by a macrophage.
Introduction: An antigen is a large molecule. It may be made up of proteins or polysaccharides. A single antigen has several binding sites that are called epitopes. Each antibody binds to a specific epitope of an antigen. An antibody is a Y-shaped protein molecule that consists of four polypeptide chains. There are two identical heavy chains and two identical light chains connected by a disulfide bond. Antibody binds to the antigen receptor of pathogens like bacteria or virus.

Consider a pencil-shaped protein with two epitopes, Y (the “eraser” end) and Z (the “point” end). They are recognized by antibodies A1 and A2, respectively. Draw and label a picture showing the antibodies linking proteins into a complex that could trigger endocytosis by a macrophage.
How are antibodies unique? Please discuss the structure of an antibody. What are the V and C regions? Discuss how the few hundred genes involved are capable of making endless amounts of antibodies. Besides medical treatment what is another way antibodies can be used?
For the diagram below, all of the following
statements are true EXCEPT:
Antigen-
binding
site
V C
Heavy chain
V
Light chain
S.S.
Fc (stem) region c C Hinge region
None of the other four answers (All are
true statements)
Antibodies (Immunoglobulins) are composed
of four protein molecules, two identical "light"
chains and two identical "heavy" chains
Antigens bind to the "stem", composed of
the constant regions of the two "heavy"
chains
The variable (V) regions form the antigen
binding sites
The constant (C) regions determine class of
antibody

- Illustrate the structure of an antibody molecule. Label the constant and variable regions, the Fc and Fab parts, and the heavy and light chains.arrow_forwardAddition of immunoglobulin G (IgG) specific for hemoglobin to a solution of hemoglobin results in the formation of a red precipitate. In contrast, addition of the Fab fragments from this antibody to hemoglobin results in no such precipitate. What could explain this difference in results? Treatment with papain produces Fab fragments with different antigen specificity than the original IgG molecule. IgG can simultaneously bind two different antigens, whereas an Fab fragment can only bind one antigen at a time. The Fab fragments preferentially bind to other Fab fragments rather than to hemoglobin. The hemoglobin molecule antibody-binding sites can bind IgG molecules, but cannot bind Fab fragments.arrow_forwardWhich antibody type description among A- D is falsely characterized?
