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 organic molecule is found in Self antigens in our cell membrane?
Self antigens in our cell membrane are primarily composed of glycoproteins and glycolipids. These molecules consist of proteins or lipids bonded to carbohydrate chains, which play a crucial role in cell recognition and immune response. The specific arrangement of these carbohydrates helps the immune system distinguish between self and non-self entities, contributing to the body's ability to tolerate its own cells while responding to foreign invaders.
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.
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 does a B cell tell the difference between an invader cell and a body cell?
Antigens work as bar-codes to help the immune system differentiate between body cells and pathogens. Normally the body will not attack its own cells, but is programmed to attack those with foreign antigens.
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.
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.
What is the function of surface antigens on RBCs?
Surface antigens on red blood cells (RBCs) play a crucial role in determining blood type and facilitating immune responses. These antigens, such as A, B, and Rh factors, are proteins and carbohydrates that help the immune system recognize self from non-self cells. When blood is transfused, the presence of incompatible antigens can trigger an immune reaction, leading to potentially serious complications. Additionally, these antigens are involved in various physiological processes, including cell signaling and adhesion.
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.
Autoantibodies are produced against?
self-antigens
