Which integral proteins with carbohydrates sugars attached that stick out on the exterior surface of cell membranes help recognize self?
Receptor proteins
What is the difference between type a blood cells and type b cell?
Type A and B red blood cells differ in the antigens they express on the cell surface. The still carry out the same tasks (transportation). The antigens on the surface of these cells are what is recognised by the immune system - so that it knows the cell is part of the body and not foreign.
What is the basic macromolecule that all cell membranes are composed of?
Cell membranes are primarily composed of a phospholipid bilayer. Amongst these layers there are proteins embedded both on the inner and outer surfaces and through the layer often acting as channels for other substances.The outer surface of the membrane contains carbohydrate chains attached to surface proteins.The phospholipid bilayer also contains cholesterol.All cell membranes are composed of:PhospholipidsProteinsCarbohydratesCholesterol
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).
Do parietal membranes cover the surface of organs?
No
A persons blood type depends on the presence or absence of certain proteins called?
A & B antigens on the surface of the read blood cells
Is blood typed based on the proteins fund in the plasma?
Blood type is based on the antigens found on the surface of the red blood cells. It's not based on proteins found in plasma.
Which integral proteins with carbohydrates sugars attached that stick out on the exterior surface of cell membranes help recognize self?
Receptor proteins
What does N1H1 stand for?
Hemagglutanin & Neurominadase are surface antigens. The number '1' refers to the specific sub-type of those antigens. The sub-types differ in their basic structure.
What explains the difference between a pancreas cell and a skin cell?
Even though they both contain the same genetic material (DNA) and will share certain similar properties such as surface antigens they are different because they have different genes turned on and off and so express different proteins.
According to the clonal selection theory foreign antigens select and interact with surface receptors only on the membranes of those specific lymphocytes that are genetically capable of making antibod?
False
What are types of anitgen's?
There are several types of antigens, including proteins, carbohydrates, lipids, and nucleic acids. Antigens can be found on the surface of pathogens like viruses and bacteria, as well as on the surface of foreign cells or substances that enter the body. They stimulate the immune system to produce antibodies and mount an immune response.
What is the difference between type a blood cells and type b cell?
Type A and B red blood cells differ in the antigens they express on the cell surface. The still carry out the same tasks (transportation). The antigens on the surface of these cells are what is recognised by the immune system - so that it knows the cell is part of the body and not foreign.
Which group is the universal donor and why?
O negative blood group is universal donor, it is bcz it haz no agglutinogen (antigens which r specific proteins on the surface of RBCs), so when transfused there will be no agglutinogen in it to react with agglutinins(defencive prteins /antibodies) present in the recipients blood. O (oh) is actually zero that indicates that no antigens are present on RBC surface.
What is antigenic drift?
The genome of viruses can mutate over time through a variety of mechanisms. Some viruses are more prone to these mutations than others. When the genome changes, this changes the proteins that are expressed by the virus, included the proteins that are present on the surface of the virus. These proteins are the antigens that are recognised by the host immune system and which trigger the immune response. Antigenic drift is when the genome of the virus mutates thus changing the antigens expressed by the virus. This means that an individual immunized against a virus may not be protected if the virus undergoes antigenic drift as the proteins present of the surface of the virus are not the same as the virus against which the individual was immunized.

How does the body react when antibiotics kill M. leprae?
When antibiotics kill M. leprae, antigens (the proteins on the surface of the organism that initiate the body's immune system response) are released from the dying bacteria.
