What typoes of cells produce antigens?
All cells produce antigens, or cell surface markers. The only question is whether the antigens are self antigens which means they belong in the body or they're foreign antigens which means they are an invading bacteria or virus (or a cancerous cell).
What is used to make the lipid bilayer found in cell membranes in the body?
Lipid bilayers found in cell membranes are mainly composed of phospholipids, which consist of a hydrophilic head and hydrophobic tails. These phospholipid molecules self-assemble to form a double layer, creating a barrier that surrounds and protects the cell.
What are molecules on the outer surface of a cell that identify it as long friend or for?
Molecules on the outer surface of a cell that identify it as "self" or "foreign" are called antigens. These antigens play a crucial role in the cell's ability to distinguish between its own cells and potentially harmful foreign cells. The recognition of self-antigens helps the immune system to tolerate the body's own cells while identifying and attacking foreign invaders.
Which integral proteins with carbohydrates sugars attached that stick out on the exterior surface of cell membranes help recognize self?
Glycoproteins are integral proteins with carbohydrate sugars attached that stick out on the exterior surface of cell membranes to help recognize self. They play a crucial role in cell recognition and immune response by distinguishing between self and non-self cells.
Is an antigen a self cell?
No, an antigen is not a self cell. Antigens are molecules that can trigger an immune response in the body. They can be part of foreign substances like bacteria or viruses, as well as self-substances that are recognized as foreign by the immune system.
Where are the antigens of the ABO blood group are located?
The antigens of the ABO blood group are located on the surface of red blood cells. These antigens determine a person's blood type (A, B, AB, O) based on the presence or absence of specific sugars on the red blood cell membrane.

How did cell membranes first appear on Earth?
There is not yet a definitive answer as to how cell membranes first evolved. One hypothesis is that cell membranes are descendant from naturally occurring micelles which combined with the first self-replicating molecules quite coincidentally. Another possibility is that cell membranes evolved as a competetive mechanism through active selection.
How does a B cell tell the difference between an invader cell and a body cell?
B cells recognize invaders by binding to specific antigens on their surface that are not present on body cells. If a B cell encounters an invader with matching antigens, it will be activated to produce antibodies against the invader, while sparing body cells that do not display those antigens.
Are antigens self cells?
The immune system is usually non-reactive against "self" antigens under normal conditions.
Which integral proteins with carbohydrates sugars attached that stick out on the exterior surface of cell membranes help recognize self?
Glycoproteins are integral proteins with carbohydrate sugars attached that stick out on the exterior surface of cell membranes to help recognize self. They play a crucial role in cell recognition and immune response by distinguishing between self and non-self cells.
Autoantibodies are produced against?
self-antigens
Are membranes a body cells?
If your question is "are membranes body cells?" the answer is no. Like the skin around your body is the boundary of your physical self so the membrane is the boundary around an individual cell.
What substances is NOT typically perceived as an antigen?
Self-antigens
What is an example of a self antigen?
A or B antigens of blood cells
