Question

Which of the following pairs is matched incorrectly?

a. Antigen : foreign substance of many different types
b. BCRs : immunoglobulins
c. Helper T cell : kills pathogen-infected cells
d. Plasma cell : involved in antibody secretion
e. T-cell activation : cell division and differentiation are both observed

Answer 1

The incorrect match is c. Helper T cells do not kill pathogen-infected cells; instead, they aid the immune response by releasing cytokines.

Step-by-step explanation:

a. Antigen: a foreign substance of many different types

b. BCRs: immunoglobulins

c. Helper T cell: kills pathogen-infected cells (matched incorrectly)

d. Plasma cell: involved in antibody secretion

e. T-cell activation: cell division and differentiation are both observed

The incorrect match is c. Helper T cell: kills pathogen-infected cells. In fact, helper T cells do not kill pathogen-infected cells; they stimulate other immune cells by releasing cytokines, while cytotoxic T cells are responsible for the killing of infected cells.
