Question

Antigen A and antibody B are present in which blood group?
A. A
B. O
C. B
D. AB

Answer 1

Hint: Proteins from the blood group antigen perform a number of roles within the red blood cell membrane. These protein functions involve transferring other proteins and molecules in and out the cell, preserving the shape of the cell, connecting them to other cells and molecules and taking part in chemical reactions.

Complete Answer:
First we should know about antigens present in blood to answer this question.
- Blood is categorized into various categories according to the appearance or lack of molecules on the surface of a red blood cell in a person's body called antigens.
- Antigens decide the form of blood, which may be proteins or sugar molecules complexes (polysaccharides). The genes in the antigen community in the blood provide guidance for the creation of antigen proteins.

Now, let us find the solution from the option.
-Antibodies are a special form of antibody of the immune system. That is known as immunoglobulins.
-The antigens exist on the RBC surface.
-The antibodies are found in the serum
-The antigen found at the RBC surface of blood group A is antigen A.
-The Antibody in the serum is Anti-B

Thus, the correct option is (A) i.e. A.

Note: Antibodies are rendered against blood cells of type B (anti-B antibodies), which target and kill blood cells of type B. This kind of discrepancy in the form of blood will lead to sickness. Few forms of blood are correlated with more serious immune reactions than others.
