Question

Which statement best describes the difference in responses of effector B cells (plasma cells) and cytotoxic T cells?

Answer 1

B cells secrete antibodies against a virus; cytotoxic T cells kill virus-infected cells.

Step-by-step explanation:

B cells or white blood cells function in the humoral immune response of the adaptive immune system with the help of secreting antibodies against a virus.

Cytotoxic T cells are known as effector cells which destroy tumor cells, virus infected cells, and tissue grafts which present in the cytosol. Cytotoxic T cells help to keep target specific antigens, and bound together during antigen specific activation. They are also known as the part of the cell meditated immune response.

Answer 2

B- cells secrete antibodies against pathogens and cytotoxic T cells kill cells infected with pathogens.

Step-by-step explanation:

When B cells interact with any antigens it gets divided into B plasma cells and B memory cells. Plasma B cells release antibodies against the antigen or pathogen present in the blood. These antibodies bind on the epitope of antigen and helps its destruction by phagocytic cells.

The process of pathogen elimination by cytotoxic T cell is quite different. Cytotoxic T cell interact with the pathogen-infected cell and release cytotoxic enzymes which kills the pathogen-infected cell.

So B- cells secrete antibodies against pathogens and cytotoxic T cells kill cells infected with pathogens.
