Question

what is happening in step 1?
the antibodies on the b lymphocyte are ____________ to an antigen on a virus.
these antigens are ____________ and identify the pathogen
what happens when an antibody that is attached to a b cell recognizes an antigen?
helper t cells ____________ this b cell to divide into plasma cells to produce antibodies and memory b cells.
antibodies ____________ the antigens on the pathogen
keep in mind...
even though t cells are mostly involved in cell - mediated immunity, they also important in humoral immunity, as t cells stimulate b cells to grow and divide rapidly into plasma cells and memory b cells.
____________ are the main weapon in humoral immunity

Explanation:

In the immune - response process, antibodies on B lymphocytes bind specifically to antigens on pathogens. Antigens are unique molecular markers. When a B - cell antibody recognizes an antigen, helper T - cells stimulate the B - cell to divide. Antibodies then neutralize the antigens. Antibodies are the main weapon in humoral immunity.

Answer:

What is happening in step 1?

• The antibodies on the B lymphocyte are binding specifically to an antigen on a virus.
• These antigens are unique molecular markers and identify the pathogen.

What happens when an antibody that is attached to a B cell recognizes an antigen?

• Helper T cells stimulate this B cell to divide into plasma cells to produce antibodies and memory B cells.
• Antibodies neutralize the antigens on the pathogen.
