Question
What immunoglobulin rises quickly during secondary immune response?
- Group of answer choices:
- IgG
- IgA
- IgM
- IgE
Solution
The immunoglobulin that rises quickly during a secondary immune response is IgG.
Here's a step-by-step explanation:
-
The immune system has a primary and secondary response to foreign substances, such as bacteria or viruses.
-
During the primary immune response, the body is exposed to an antigen for the first time. This response is slow because the immune system has to produce cells that recognize the antigen. The main immunoglobulin involved in the primary immune response is IgM.
-
The secondary immune response occurs when the body is exposed to the same antigen again. This response is faster and more effective because the immune system has "remembered" the antigen from the first exposure.
-
During the secondary immune response, the body produces a large amount of IgG. This immunoglobulin is very effective at fighting the antigen, and its levels can remain high for a long time, providing long-term protection against the antigen.
-
Therefore, the immunoglobulin that rises quickly during a secondary immune response is IgG.
