In order for a lymphocyte to respond to an antigen, the antigen must
• bind to the DNA of the lymphocyte.
O depolarize the lymphocyte.
• be phagocytized by the lymphocyte.
O bind to specific receptors on the lymphocyte membrane.
• enter the cytoplasm of the lymphocyte.
• bind to specific receptors on the lymphocyte membrane.
The correct answer is: bind to specific receptors on the lymphocyte membrane.
In order for a lymphocyte to respond to an antigen, the antigen must bind to specific receptors on the lymphocyte membrane. Lymphocytes have membrane-bound receptors that can recognize and bind to specific antigens. When an antigen binds to these receptors, it triggers a signal transduction pathway within the lymphocyte, leading to activation and immune response.
