Question

Quizplus · Accepted Answer

The primary response to antigen exposure is not delayed by the memory cell stage as memory cells are only produced after the primary response. The primary response depends on antigen triggering the appropriate B cell, requires B cell differentiation into plasma cells, and results in a gradual, sustained rise in circulating antibodies that peaks 1 to 2 weeks after the initial exposure.
