Detailed explanation-1: -Antibodies attach to a specific antigen and make it easier for the immune cells to destroy the antigen. T lymphocytes attack antigens directly and help control the immune response. They also release chemicals, known as cytokines, which control the entire immune response.
Detailed explanation-2: -Antigens are classically defined as any foreign substance that elicits an immune response. The antibody specificity for any given antigen is underscored by its unique structure, which allows antigen binding with high precision.
Detailed explanation-3: -Although antibodies can recognize an antigen and lock onto it, they can’t destroy it without help. That’s the job of the T cells. They destroy antigens tagged by antibodies or cells that are infected or somehow changed.
