The B lymphocyte Response

Question 1

B-lymphocytes and the ……………..

Answer 1

humoral immune response

Question 2

B-lymphocytes (B cells) remain in the bone marrow until they are mature and then

Answer 2

spread through the body, concentrating in lymph nodes and the spleen

Question 3

Millions of types of B-lymphocyte cells are produced within us because as they mature the

Answer 3

genes coding for antibodies are changed to code for different antibodies

Question 4

Once mature, each type of B-lymphocyte cell can make

Answer 4

one type of antibody molecule

Question 5

Once mature, each type of B-lymphocyte cell can make one type of antibody molecule
At this stage, the antibody molecules do not leave the B-lymphocyte cell but remain in the …………

Answer 5

cell surface membrane

Question 6

Part of each antibody molecule forms a

Answer 6

glycoprotein receptor that can combine specifically with one type of antigen

Question 7

Part of each antibody molecule forms a glycoprotein receptor that can combine specifically with one type of antigen

If that antigen enters the body, B-lymphocyte cells with the correct cell surface receptors will be able to

Answer 7

recognise it and bind to it (clonal selection

Question 8

These specific B-lymphocytes divide repeatedly by mitosis (clonal expansion) and differentiate into two main types of cell:

Answer 8

Plasma cells
Memory cells
