Question

If you suspect deficiency of antibodies in a person, to which of the following would you look for confirmatory evidence?

• A. Serum albumins
• B. Fibrinogen in the plasma
• C. Serum globulins
• D. Haemocytes

Answer 1

The correct option is C

Serum globulins

The correct option is C

Explanation of the correct option:

1. The globular proteins that makeup antibodies are found in serum and plasma.
2. WBC (leukocytes), RBC (erythrocytes), platelets, and other clotting factors are absent from serum.
3. In the blood serum, antibodies help to create 17–20 percent of the total protein. There are four varieties of serum globulin based on their characteristics.
4. Globulins of type Ia, Globulins of type IIa, alpha globulins, beta globulin.
5. The gamma globulin class includes antibodies.
6. They are crucial components of human blood since their shortage can result in many disorders (such as gammopathy) and is also bad for health.

Explanation of the incorrect option:

Option A:

1. Human blood plasma contains significant amounts of the protein serum albumin. I
2. It is crucial for maintaining tissue fluid balance and controlling plasma volume.

Option B:

Plasma protein called fibrinogen is in charge of regulating regular blood clotting.

Option D:

In bivalves, circulating haemoglobin helps with five different physiological processes: excretion, digestion and transport of nutrients, wound and shell repair, and internal defence.

Final answer: Therefore, to know whether the person has a deficiency of antibodies or not, serum globulin is tested.
