Answer:

antibodies

Step-by-step explanation:

Antibodies are soluble mediators of the immune system.

They are also known as immunoglobulins and are bifunctional molecules.

They consist of polypeptide chains with an antigen binding site and a site that carries out the biological activity of the molecule.

Antibodies are expressed on the cell surface of B cells. When these B cells are stimulated by antigen, they differentiate into antibody-secreting plasma cells. The antibodies secreted then serve as effector molecules for cells functioning in the innate and/or adaptive immune systems.

For example, particular antibodies trigger the activation of the classic complement pathway.
