The following are steps in the cell-mediated immune response. what is the correct sequence for these steps?
a) several cycles of mitosis occur.
b) antigen is engulfed and presented by a macrophage.
c) cytotoxic t cells migrate to focus of infection.
d) t cells with specific receptors recognize the antigen.
e) t cells differentiate into cytotoxic t cells or t memory cells.
f) cytotoxic t cells release perforin and/or lymphotoxin.

Steps in correct sequence:  

B) – D) – A) – E) –C) – F)  

Explanation:

Cell-mediated immunity is a particular adaptive immune response. This type of immune response fight against intracellular infections such as viruses, some bacteria, fungi, and Plasmodium. Cell- mediated immune response is activated by TH1 cells.

Steps in correct sequence given below:

B) Antigen is engulfed and presented by a macrophage.  

D) T cells with specific receptors recognize the antigen.  

A) Several cycles of mitosis occur.  

E) T cells differentiate into cytotoxic T cells or T memory cells.  

C) Cytotoxic T cells migrate to focus of infection.  

F) Cytotoxic T cells release perforin and/or lymphotoxin.

It converts nitrogen into a form that humans can obtain by eating other organisms.
