Bio 200 RQ 9-1
Which of the following occur after a B cell fully activates? - answer-The cell goes
through mitosis
-Some of the daughter cells become "memory" cells and stick around for a long time
-Some of the daughter cells become "plasma" cells and secrete a lot of free antibody
What can free antibody do to help cure an infection? - answer-antibody binds to
pathogens making their outer proteins "blocked" so they cannot bind and infect cells
-antibody binds to pathogens, marking them to be "eaten" (destroyed) by other cells
such as phagocytes
After exposure to an antigen and having a normal immune response, what happens if
the body is exposed to the same antigen a second time? - answerThe body's second
response is faster and stronger (more antibody produced)
What does clonal selection refer to? - answera process where the B cells with BCRs
that best "match" an antigen proliferate most rapidly, making them more prevalent in the
body relative to other B cells
