Which of the following statements are true for B cells?
Which of the following statements are true for B cells?
The correct option is D Plasma B cells secrete antibodies to neutralise the antigen and are short lived
When there is an infection in the body, the B cells rapidly divide and produce plasma cells. The plasma cells are highly efficient and produce 2000 antibody molecules per second. Millions of antibodies are produced by the plasma cells specific to the antigen. The antibodies bind the pathogen and enable its phagocytosis by the macrophages and other phagocytes. However, the B cells also divide and produce another type of cells called memory B cells. Memory B cells keep circulating in the blood for longer time periods and also specialise in retaining the memory of a particular antigen. So, if the same antigen is encountered again, it is rapidly neutralised, initiating an effective secondary response.
