Antibodies and Antigens

Antibodies are Y-shaped proteins that are highly specific to the antigens on a pathogen's surface.

Which type of cell produces antibodies?

What is Antibodies and Antigens?

"An antibody is a large, Y-shaped protein used by the immune system to identify and neutralize foreign objects such as pathogenic bacteria and viruses."

Question 1

What is the role of antibodies in the immune system?

Question 2

In GCSE Biology, what is the role of antibodies in the immune system?

Question 3

Select what is the role of antibodies in the immune system?

Specific Response

Lymphocytes produce antibodies when they detect unique antigens.

Antibodies bind to pathogens, clumping them together.

This makes it easier for phagocytes to destroy them.

Exam Tip

Memory cells "remember" the specific antibody needed for a pathogen, providing immunity.
