Question

Antibody formation and immunity production is done by a protein called globulin, which is
present in the
A. Stroma of RBC
B. Hemoglobin of RBC
C. Plasma
D. Blood platelets

Answer 1

Hint:- Blood is the fluid component of the body, and it consists of various cells and other components, and the cells such as red blood cells, white blood cells platelets, etc. And it also consists of 55% of the liquid part, in which all these blood cells are suspended along with some proteins and other components.

Complete answer:
1. Globulin is an important component of protein that is found in the plasma along with the other protein components such as albumin, etc.
2. Among all of the plasma proteins, this globulin is made up of high molecular weight, and it is generally not soluble in pure water, but soluble in some dilute solutions, and the globulin proteins are mainly synthesized by the liver and some of the immunoglobulins which are one types of globulins are produced by immune cells.
3. There are majorly four types of globulin proteins, they are alpha 1, alpha 2, and gamma globulins, and among that gamma globulin, some type is immunoglobulins which are produced by the plasma cells.
4. These immunoglobulins act as antibodies and play an important role in identifying the various pathogens such as bacteria, virus, etc.
5. This immunoglobulin helps in identifying certain pathogens or part of pathogens as these antibodies have V-shaped structures, with which they present the particles so that other cells of the immune system come and attack the pathogen.
So, the correct option is C.

Note:- Immunoglobulins are of one of the types of gamma globulins which are come under the globulins that are present in the plasma of the blood, and other globulins such as alpha, beta, and some other gamma globulins have other functions such as for producing oncotic pressure and other important functions in the body.
