Answer:

An antigen is a foreign substance such as a protein or polysaccharide to which lymphocytes respond whereas an antibody is a globular protein that reacts with an antigen to eliminate the antigen.

An antigen is a foreign substance such as a protein or a polysaccharide to which lymphocytes respond, whereas an antibody is a globular protein that reacts with an antigen to eliminate the antigen.

What is Antigen?

An antigen may be defined as a foreign substance that invades the body of living entities and stimulates the immune response.

An antigen is detected by immune cells and an antibody is constructed against it.

When an antibody is bound to its antigens, through antigenic specificity, such globular proteins digest the antigenic parts and finally eliminate them from the body.

Therefore, it is well described above.
