Question

Which statement is not correct about the antibodies?

a. They are protein molecules that bind to the specific antigens
b. They are produced by memory B cells
c. They consist of 2 heavy chains and 2 light chains
d. They contain fixed and variable regions
e. They are also called immunoglobulins

Answer 1

b. They are produced by memory B cells

Step-by-step explanation:

The rapid cell division in activated B cells is followed by the differentiation of daughter cells into the plasma cells. The plasma cells are the precursor for antibodies and memory B cells. The antibodies kill the antigens while memory B cells are long-lived cells.

Hence, antibodies are not produced by memory B cells but by plasma cells.
