Question

Which of the following happens when infected body cells are detected during a cell mediated immune response A. Helper T cells divide and activate cytotoxic Tcells, which destroy the infected cells. B. Memory T cells divide and form helper T cells, which destroy the infected cells . C. B lymphocytes divide and activate memory B cells, which destroy the infected cells D. Memory B cells divide and form plasma cells which destroy the infected cells

Answer 1

The correct answer would be option A.

Explanation:

Cell mediated immunity in which antibodies are not required. It is mediated by phagocytes, cytokines released for specific antigens, and antigen-specific cytotoxic T-cells. cell mediated immunity is refers to the fact that the response is driven by cytotoxic cells.

Cell-mediated immunity can be obtained through T cells from someone who is immune to the particular infection.

Helper T cells help activate cytotoxic T cells and macrophages to attack infected cells.

Thus, the correct answer is option A.

Answer 2

The correct answer is option A. "Helper T cells divide and activate cytotoxic Tcells, which destroy the infected cells".

Step-by-step explanation:

Cell-mediated immunity, or cell immune response, is the type of immune reaction that does not involve the creation of antibodies. In this type of response, when infected body cells are detected Helper T cells divide and activate cytotoxic T cells, which destroy the infected cells. Helper T cells start to replicate and activate cytotoxic T cells by interacting with antigen-presenting cells, the cells that recognize the infected body cells.
