6.2.6 - B Cell Response

Question 1

What Are B Cells & Where Are They Produced?
(2 Points)

Answer 1

~ Type of white blood cell, involved in the specific immune response.

~ Produced and mature in the bond marrow.

Question 2

What Is the Cell Surface Of B Cells Covered With?

Answer 2

Antibodies receptors, specific to a complementary antigen to form an antigen-antibody complex.

Question 3

Describe The B Cell Response
(4 Points)

Answer 3

~ When a corresponding antigen enters the body, B cells with the correct antibodies will recognise it and bind to it, forming an antigen-antibody complex.

~ This binding along with the cell signalling molecules produced by T helper cells activates the B cell.

~ Once activated B cells divide by mitosis, producing clones of the original activated B cell.

~ They then differentiate into 2 cells -> B effector cells (Then form plasma cells) and B memory cells.

Question 4

What Is The Role Of B Memory Cells?

Answer 4

Remain in the blood to allow a faster immune response to the same pathogen in the future.
