An antigen is a biomolecule, such as a protein or sugar, that binds to a specific antibody. An antibody/antigen interaction may stimulate an immune response. Not every biomolecule is antigenic and not all antigens produce an immune response. B cells are the major cell type involved in the humoral immune response.
The key biomolecule involved in the immune system is a protein known as an antibody. These are produced by B cells and help the immune system recognize and destroy foreign substances like bacteria or viruses.
The biomolecule that has significant involvement in the immune system is a group of proteins known as antibodies or immunoglobulins. These antibodies are produced by certain types of white blood cells (B cells). They play a crucial role in the immune response by recognizing and binding to specific antigens such as bacteria or viruses, enabling other parts of the immune system to destroy these foreign substances more effectively. For example, if a person becomes infected with a virus, the immune system will produce antibodies specific to that virus. Once these antibodies attach to the virus, they basically mark it for destruction by other cells in the immune system.

It was found on the American Cancer Society website, and websites are unreliable.
It is information that is used for a variety of purposes and not just gathered for research.
It is from a self-reporting survey, and teens may not want to answer the questions honestly.
The information may be unreliable due to being outdated, sourced from a potential bias platform, not specifically gathered for research purposes, or collected from potentially unreliable self-report surveys from teens.
There are a few reasons why the data in question may be unreliable. Firstly, if the information is too old it may not accurately reflect current conditions or understandings. This could make it unreliable for contemporary research or decision-making purposes.
Secondly, while websites such as the American Cancer Society can be reliable sources of information, it is important to consider that not all websites are. Some may not be up-to-date, be subject to bias, or lack comprehensive peer review.
Thirdly, if the information is used for a variety of purposes rather than specifically gathered for research, it may lack the specific relevancy, depth, or focus necessary for certain studies which can limit its reliability.
Lastly, relying on self-reported data, especially from a demographic like teens, can introduce bias as participants may not feel comfortable answering honestly or may not recall information accurately.
