ANATOMY

Detailed explanation-1: -An antibody (formally called immunoglobulin) is a large Y-shaped glycoprotein produced by B-cells and used by the immune system to identify and neutralize pathogens. Antibodies are produced by B cells, and are either secreted into circulation or remain expressed on the surface of the B cell.

Detailed explanation-2: -B-cells produce antibodies to fight bacteria and viruses. These antibodies are Y-shaped proteins that are specific to each pathogen and are able to lock onto the surface of an invading cell and mark it for destruction by other immune cells.

Detailed explanation-3: -Antibodies are Y-shaped proteins produced as part of the body’s immune response to infection. They help eliminate disease-causing microbes from the body, for instance by directly destroying them or by blocking them from infecting … cells.

Detailed explanation-4: -Each antibody structure consists of two heavy chains and two light chains, which join to form a Y-shaped molecule. Each type of antibody has a different amino acid sequence at the tips of the “Y” which is why each antibody is shaped differently.

Detailed explanation-5: -Antibody binding also marks invading pathogens for destruction, mainly by making it easier for phagocytic cells of the innate immune system to ingest them.
