About This Quiz & Worksheet

This quiz and corresponding worksheet will test you on your knowledge of antibody structure. You'll need to know about concepts such as light and heavy chains and antigens to pass the quiz.

Quiz & Worksheet Goals

Use this quiz to review:

  • The composition of Y-shaped antibodies
  • How an antibody switches isotypes
  • Antibody production
  • Antigen features
  • The paratope

Skills Practiced

This worksheet and quiz combo will allow students to practice the following skills:

  • Distinguishing differences- compare the paratope to the epitope
  • Information recall- access your knowledge of the four chains of protein
  • Knowledge application- use your knowledge to answer questions about the composition of antibodies

Additional Learning

To learn more about how antibodies operate, review the accompanying lesson on The Structure of Antibodies. This lesson covers the following objectives:

  • Understanding the four chains of protein making up antibodies
  • Identify the region located at the end of the light and heavy chains of an antibody
  • Define the term associated with part of the antibody that is the same across a unique isotope of immunoglobulin
  • Identify the part of the variable domain of an antibody that recognizes and binds to an antigen
