B and T Lymphocytes Immune Response — NEET Biology
🔥 Predicted for NEET 2027The primary and secondary immune responses are carried out with the help of two special types of lymphocytes present in our blood, i.e., B-lymphocytes and T-lymphocytes.
Adjacent to a frequently-asked paragraph in the same chapter.
Consider the following statements about acquired immunity: 1. It is pathogen-specific and characterised by memory. 2. Primary immune response is of high intensity while secondary response is weaker. 3. T-lymphocytes mediate cell-mediated immunity (CMI). 4. Antibody structure consists of two light and two heavy peptide chains, represented as H₂L₂. 5. Antibody-mediated response is also called humoral immune response. Which of the above statements are correct?
