MULTIPLE CHOICE QUESTION

When a B cell encounters its antigen, that antigen provokes the humoral immune response in which antibodies specific for that antigen are made

True
false

MULTIPLE SELECT QUESTION

What is true about the activation and differentiation of B cells?

naïve B cells activate when matching antigens bind to is surface recptors and cross-link adjacent receptors together
antigen binding is followed by receptor mediated endocytosis of the cross-linked antigen-receptor complex
clonal selection is followed by proliferation and differentiation into effector cells
usually interactions with T cells are required to help B cells achieve full activation
most clones differentiate into plasma cells but some become long-lived memory cells

What is true about plasma cells?

they are the anti-body secretingcells of the humoral response
develop elaborate internal machinery (rough ER) needed to secrete 2000 antibodies/second
function for 4-5 days and then dies
the secreted antibodies circulate in the blood/lymph where they find free antigens marking them for destruction by the innate or adaptive immune system

What is true about memory B cells

clone cells that do not differentiate into plasma cells
mount an almost immediate huoral response if they encounter the same antigen again
capable of secreting antibodies
only live 4-5 days

MULTIPLE SELECT QUESTION

30 sec • 1 pt

The primary immune response occurs only for when the body first sees an antigen/pathogen, which of the following is true about the primary immune response

typically has a lag period of 3-6 days after antigen exposure
there is a lag as the few B cells specific for that antigen proliferate and for the clones to become B cells
after the mobilization period, plasma antibody levels rise and reach a peak in about 10 days then decline
immune responses are more prolonged

MULTIPLE SELECT QUESTION

What is true about the secondary immune response?

describes when a person is re-exposed to the same antigen whether it is the 2nd or 22nd time
immune responses are faster
immune responses are more prolonged
immune responses are more effective since the immune system has already been primed/sensitized
memory cells are on high alert and ready to respond
