Each cytotoxic T cell "dies" after inactivating an antigen.

A. True
B. False


Sagot :

Final answer:

Most cytotoxic T cells do not die after inactivating an antigen, as some of them become memory cells to provide immunity upon re-infection.


Explanation:

False. After bringing an infection under control, most cytotoxic T cells die off, but some remain as memory cells. These memory cells facilitate a rapid immune response upon re-infection by producing more cytotoxic T cells specific to the antigen.
