Explanation

Question 21 of 47

1

Order the steps in the antibody production process.

In response to the antigen protein, the naïve B cell begins reproducing, creating IgM plasma cells and memory cells.
IgG memory cells remain in the body, preparing the body for a second infection.
Proteins on the surface of the pathogen enter the lymphatic system.
Proteins from the surface of the antigen enter the lymph nodes.
Plasma cells excrete antibodies to deal with the antigen.
The proteins encounter a naïve B cell that reacts to them.
As antibodies deal with the infection, some cells mutate into IgG cells.
The body is infected with a disease, and pathogens enter the system.
