humoral responses - b cells

Question 1

b cells

Answer 1

white blood cells involved in specific immune responses

they mature in the bone marrow

Question 2

memory b cells

Answer 2

dont make antibodies

can divide by mitosis to make plasma cells rapidly if they collide with familiar antigens

Question 3

antibodies

Answer 3

soluble

flexible

transports in bodily fluids

quaternary structure

can bind to antigens to clump together

Question 4

agglutination

Answer 4

antibodies bind to antigen forming an antigen-antibody complex

its flexible so it can bend and flex to attach to antigen

makes it easier to locate phagocytes and destroy pathogens

Question 5

b cell activation

Answer 5

antigens will collide with complementary antibody on the b cell (takes in the antigen by endocytosis and presents it on its cell surface membrane

b cell collides with the helper t cell receptors - this activates the b cell to go through clonal expansion and clonal selection

b cell undergoes mitosis to make large numbers of cells that differentiates into plasma cell or memory b cells

plasma cells make antibodies - b cells divide rapidly into plasma cells when reinfected with the same pathogen to make large numbers of antibodies rapidly
