Question

what are antibodies and how they work​

Answer 1

Answer:

Antibodies are Y-shaped proteins produced as part of the body's immune response to infection. They help eliminate disease-causing microbes from the body, for instance by directly destroying them or by blocking them from infecting cells.

Answer 2

Antibodies are Y-shaped proteins that bind to the body's foreign invaders and signal the immune system to get to work. Antibodies are specialized, Y-shaped proteins that bind like a lock-and-key to the body's foreign invaders — whether they are viruses, bacteria, fungi or parasites.
