Immunity ( 54 Questions)
The secondary immune response is characterized by:
The secondary immune response is faster and stronger compared to the primary immune response, not delayed and weaker.
The secondary immune response involves the activation of memory B cells and memory T cells, not naive B cells and T cells.
The secondary immune response is faster and more potent than the primary immune response due to the presence of memory B cells and memory T cells. These memory cells "remember" the specific antigen from a previous encounter, allowing for a quicker and more effective immune response upon re-exposure to the same antigen.
The primary immune response is characterized by the production of IgM antibodies initially, but during the secondary immune response, the production of IgG antibodies predominates, which are more effective in neutralizing antigens.
Explanation: The secondary immune response is faster and more potent than the primary immune response due to the presence of memory B cells and memory T cells. These memory cells "remember" the specific antigen from a previous encounter, allowing for a quicker and more effective immune response upon re-exposure to the same antigen.
