How does protein contribute to the production of antibodies in the immune system?

Proteins play a crucial role in the production of antibodies in the immune system. Antibodies are a type of protein that help the immune system recognize and fight off harmful pathogens like bacteria and viruses. When the body detects an invader, specialized cells called B cells produce antibodies that specifically target and neutralize the pathogen. These antibodies are made up of protein molecules that bind to the surface of the pathogen, marking it for destruction by other immune cells. In this way, proteins are essential for the immune system's ability to defend the body against infections.
