They are Proteins =)
An antibody is a protein.
No, an oxygen atom is O but oxygen exists as a molecule O2. A macromolecule is a large one. An example of a macromolecule would be DNA or a protein or a polymer. Oxygen does not fit this category.
carbohydrates
They are antibodies that you are born with an occur without exposure to foreign. A good example would be found in an O negative individual. They have A and B antibodies in their plasma.
proteins
Proteins are found in cells. Proteins are a macromolecule.
Antibodies belong to the class of macromolecules known as proteins. They are Y-shaped proteins produced by the immune system in response to the presence of foreign substances called antigens.

I would have said "phospholipid" except that it's hardly a "macromolecule" by my standards (I'm a polymer chemist by training).
proteins
Each antibody is made to target certain antigens (disease or virus). They then would destroy them. The antibodies stay in the body so that if the antigen attacks again, the antibodies would already be there to destroy them.
Antigens are displayed on the surface of a macrophage after the digestion of a bacterium.
no because it is in the body
