Which of the following is the correct option for decreases order of concentrations of different types of antibodies which are produced in our body ?

Options

A. IgG, IgA, IgM, IgD, IgE
B. IgM, IgG, IgA, IgD, IgE
C. IgE, IgD, IgM, IgA, IgG
D. IgE, IgD, IgA, IgG, IgM

Answer

To determine the correct order of antibody concentrations in the human body, we need to know the types of antibodies and their relative concentrations. The five main types of antibodies (immunoglobulins) produced by our body are:

1. **IgG** - This is the most abundant antibody, making up about 75% of the total antibodies in the body.
2. **IgA** - This antibody accounts for approximately 15% of the total antibodies.
3. **IgM** - This type represents about 5% of the total antibody concentration.
4. **IgD** - This is present in very low amounts, around 0.2%.
5. **IgE** - This is the least abundant antibody, with a concentration of about 0.05%.

Now, we can arrange these antibodies in decreasing order of their concentrations:

1. **IgG** - 75%
2. **IgA** - 15%
3. **IgM** - 5%
4. **IgD** - 0.2%
5. **IgE** - 0.05%

Thus, the correct decreasing order of concentrations of different types of antibodies produced in our body is:

**IgG > IgA > IgM > IgD > IgE**

Now, let’s summarize the steps:

1. Identify the five types of antibodies: IgG, IgA, IgM, IgD, IgE.
2. Determine the concentration of each antibody in the body.
3. Arrange the antibodies in decreasing order based on their concentrations.
4. Verify the order against the provided options to find the correct one.
