B cells make antibodies when they recognize antigens.
Simple the answer is an Antibody!
Antigens
When antibodies bind to the epitopes of an antigen(bacteria) via antigen receptors, the antibodies present the bacteria to a macrophages in a form that they recognize the foreign substance and engulf them. This antibody-antigen "team work" is also known as opsonization
There are two groups that recognize the protein. The Anti-Hsp65 antibodies recognize M proteins of group A streptococci. They are strong bacterial immunogens that have been linked to arthritis and autoimmunity.
The immune system does not recognize the killed bacteria, and cannot recognize that the bacteria are killed, so it begins to produce antibodies for it just as it would if the bacteria were alive.
Our bodies do have the ability to make antibodies to something we never have had contact with. These are called natural antibodies. Natural antibodies are produced by B lymphocytes in the absence of external pathogen stimulation. With their ability to recognize between self and non-self, they comprise an important first-line defense. Any problem with this formation of natural antibodies, the body would begin to attack itself. This is seen in autoimmune disorders.
A virus doesn't have to be alive for the body to produce antibodies against it. Antibodies recognize the physical appearance of a virus. By using dead viruses the immune system is taught to look out for a live virus with the same characteristics of the dead one, but you don't risk being infected by the virus.
Blood plasma is packed with proteins called antibodies. The body produces a wide variety of antibodies that will recognize and attack foreign molecules that may enter from the outside world. A person's plasma does not contain any antibodies that will bind to molecules that are part of his or her own body.
B-cells produces antibodies that target specific pathogens so t-cells can then recognize it and consume it.
This question is poorly worded. As worded--No. You can DESCRIBE exothermic or endothermic reactions on graphs, however.
