Anna [14]

Question is incomplete. Complete Question is as follows.

Antibodies are proteins that have a lock-and-key recognition for their antigen established by the antigen-binding site on the antibody. Match the antibodies in the left column to the appropriate blanks in the sentences on the right.

neither anti-A nor anti-B

anti-O

anti-AB

anti-A

anti-A and anti-B

anti-B

1) People who have the A antigen on the surface of their red blood cells have __________antibodies in their plasma.

2) People who have the B antigen on the surface of their red blood cells have  ___________ antibodies in their plasma.

3) People who have both A and B antigens on the surface of their red blood cells have ____________ antibodies in their plasma.

4) People who have neither A nor B antigens on the surface of their red blood cells have _________ antibodies in their plasma.

Answer:

1) People who have the A antigen on the surface of their red blood cells have   <u>anti-B </u>  antibodies in their plasma.

2) People who have the B antigen on the surface of their red blood cells have <u> anti-A </u> antibodies in their plasma.

3) People who have both A and B antigens on the surface of their red blood cells have  <u>neither anti-A nor anti B</u> antibodies in their plasma.

4) People who have neither A nor B antigens on the surface of their red blood cells have <u> both anti-A and anti-B antibodies</u> in their plasma.

Explanation:

The antigen present on the surface of the RBC determines the blood group of the person.

The type of antigen present on the RBC determines that which antibody will be present in the blood. Always opposite antibody is present in the blood in order to prevent the reaction of antigen antibody and prevent agglutination.

For example For A antigen , anti A antibody will never be present, always anti-B antibody will be present because if anti-A antibody will be present, it will react with the A antigen resulting in the agglutination of the blood.

similarly all the other blood group antigens are varying with the antibodies.
