Which of the following statements about antibodies is NOT true?

Antibodies are glycoproteins, also known as immunoglobulins, that play a crucial role in the immune response by identifying and neutralizing foreign objects like bacteria and viruses. They can be found in plasma and various body secretions, indicating their diverse presence throughout the body as part of the immune defense. Each antibody is designed to bind specifically to one unique antigen, showcasing how antibodies can target specific pathogens effectively.

The key point about the choice indicating that antibodies are cells is that this statement misrepresents the nature of antibodies. Antibodies are not cells; rather, they are molecules produced by a specific type of white blood cell called B cells. When activated, these B cells differentiate into plasma cells, which are responsible for the production and secretion of antibodies.

Overall, the distinction between antibodies and cells is essential to understand the immune system's functioning, emphasizing that while antibodies are critical components, they are not cellular entities themselves.
