IgM is the antibody first secreted during primary response
The specific protein made in response to a particular antigen is called an antibody.
Antibody is a protein made in response to a specific antigen. The antibody attaches to the antigen and makes it useless.
An antibody reacts to the specific antigen it is made to attach to. It is like the lock and key model; it locks onto the antigen.
An antigen is a protein made in response to a specific antigen.
An antigen may be made of either a bacteria or a virus. An antigen refers to a toxic or a foreign substance that once in the body attracts and is bound to a respective and specific antibody.
Giant turtles are what are made in response to a specific antigen. Hope I Helped!

Antibodies
Primary versus Secondary Immune ResponseThe primary immune response occurs the first time that the immune system comes in contact with the antigen. During this time the immune system has to learn to recognize antigen and how to make antibody against it and eventually gain immunological memory. This primary response takes time (about two weeks) and during this time the person experiences signs of illness. IgM antibodies are the hallmark of a new infection because they are the first antibodies made when a person is exposed to an antigen for the first time. After the body learns to make IgM antibodies, it will start making IgG antibodies to the antigen.The secondary immune response occurs the second time (3rd, 4th, etc.) the person is exposed to the same antigen. At this point immunological memory has been established and the immune system can start making antibodies immediately. The antigen usually is killed within minutes and the person is not aware that he/she was attacked. The antibodies in this response are IgG and IgA or (in the case of allergy IgE).
substance
An antibody is a y shaped molecule which is specific to a particular antigen, it is a globular protein which is made by white blood cells called lymphocytes. These defend the body against antigens (alien cells).
Anibodies are y-shaped bundles of proteins found throughout most mammalian bodies. The two prongs in the y shape are made out of an inner heavy chain and an outer light chain. The tips of the two prongs contain antigen binding sites that will react chemically to special chemicals called antigens on the cell membrane of a target cell. The antigen binding site of a specific antibody will only bind to a matching antigen, so numerous antibodies are needed to bind to all possible intruding organisms.
