In the antibody-mediated immune response, the binding of some antigen-presenting B cells to helper T cells initiates a signal transduction pathway that transforms the B cells into plasma cells, which will synthesize and secrete large quantities of antibodies-a specialized subset of proteins responsible for attaching to the antigen on the outer surface of pathogens. Which of the following describes the most relevant intracellular change to B cells as they are transformed into plasma cells? A B a breakdown of some membrane-bound proteins to allow synthesized antibodies to more readily diffuse across the membrane of the plasma cell с an increase in the surface area of the rough endoplasmic reticulum in order to allow the binding of a large number of ribosomes for antibody synthesis D an increase in the number of lysosomes in order to facilitate the storage of synthesized antibodies ahead of their transport out of the cell an increase in the volume of the mitochondria in order to increase…
