Which of the Following is Not a Step in the Activation

Question

Which of the following is not a step in the activation of a B lymphocyte?
A) Antigen presentation
B) Production of antibody-secreting plasma cells
C) Activation by helper T cells
D) Activation of cells that engage in cell-to-cell combat

Accepted Answer

The activation of B lymphocytes does not involve the activation of cells that engage in cell-to-cell combat. Instead, B lymphocytes are activated by antigen presentation, followed by activation by helper T cells, and ultimately the production of antibody-secreting plasma cells.
