Question

which of the following shows the correct sequence of events for the activation of a b cell and the subsequent destruction of a pathogen? 1 point
antigen encounter > antigen display > helper t cell binding > antibody production > phagocytosis.
phagocytosis > antigen encounter > antibody production > helper t cell binding.
helper t cell binding > antigen display > phagocytosis > antigen encounter.
antibody production > antigen encounter > helper t cell binding > phagocytosis.

Explanation:

First, a B - cell encounters an antigen. Then it displays the antigen. A helper T - cell binds to the B - cell presenting the antigen. This binding stimulates the B - cell to produce antibodies. Finally, phagocytosis occurs to destroy the pathogen.

Answer:

Antigen encounter > Antigen display > Helper T cell binding > Antibody production > Phagocytosis.
