Presented by APCs as MHC-exogenous peptide complex
What else can I help you with?
Difference between MHC class1 and MHC class2 molecules?
MHC proteins express antigens on a cell surface for T cells to identify whether the antigens presented are self or foreign. There are two classes MHC I and MHC II. They differ in which cells they require to activate depending on the pathogen present.
What 3 things are found i a liquid?
Molecules, ions, and solvent molecules are typically found in a liquid.
What membrane surface molecules bind to proteins and serve as molecular identification tags?
molecular identification tags such as phosphate group added to the Golgi prouducts aid in sorting by acting like ZIP codes on mailing labels. BIOLOGY 8TH EDITHION ( CAMPBELL ET. AL 2008)
Is citric acid a class II preservative?
No, citric acid is not considered a class II preservative. It is primarily used as a flavoring and acidifying agent in food and beverages, rather than for its preservative properties.
What term describes the class of molecules that includes starch and glycogen?
carbohydrates
What is the major class of organic molecules found in egg yolk?
major class of molecules found in egg yolk
Class II MHC molecules are found only on which of the following?
Presented by APCs as MHC-exogenous peptide complex
What is the difference between a class I MHC mechanism vs a class II MHC mechanism?
The Class I MHC molecules process endogenous(intracellular) peptides/antigens whereas the Class II process exogenous(extracellular) peptides/antigens. The Class I molecules are assembled and located in the ER whereas the Class II are assembled in the ER but located in the endosomes. When extracellular peptides are taken into the cell via receptor mediated endocytosis or phagocytosis, they will be transported into the endosomes and get degraded. This will enable the peptide generated to be loaded onto the Class II molecules. For Class I, when a bacteria or virus infect a cell, they will replicate and produce proteins. These proteins will be ubiquitinated and degraded by the proteasome. This smaller peptides can then be transported into the ER via the TAP transporters, that are complexed with the Class I molecules, to be loaded onto the Class I molecules.
Difference between MHC class1 and MHC class2 molecules?

What is the type of major histocompatibility marker that's most likely found on a liver cell?
Answer Class II MHC protein. Class II are found in membranes of antigen-presenting cells-phagocytic cells and lymphocytes. The liver performs phagocytosis and antigen presentation.
What role does the macrophage play in?
presents antigens of an engulfed pathogen in its class II MHC molecules to helper T cells, and releases IL-1
Is HLA only found on leukocytes?
HLA (human leukocyte antigen) is the name for the MHC (major histocompatibility complex) found in humans. MHC class I molecules (HLA-A, HLA-B, HLA-C) are found on pretty much all cells (some important exceptions are red blood cells). MHC Class II molecules (HLA-DQ, HLA-DP, HLA-DR) are found on special antigen presenting cells, which include B-lymphocytes, dentritic cells, and macrophages.
WHAT CLASS OF ORGANIC MOLECULES IS URACIL FOUND?
Uracil is found in the class of organic molecules known as nucleotides, which are the building blocks of nucleic acids like RNA. Specifically, uracil is a pyrimidine base that pairs with adenine during RNA synthesis. It is one of the four primary bases in RNA, alongside adenine, guanine, and cytosine.
When was DRG Kleinlokomotive Class II created?
DRG Kleinlokomotive Class II was created in 1932.
Can a Class II ball mount be used with a Class III receiver hitch?
No ... the ball diameter (and subsequent nut and fitting) are smaller on Class II.
Can a Class II ball mount can be used with a Class III receiver hitch.?
No ... the ball diameter (and subsequent nut and fitting) are smaller on Class II.
Is Xanax a Class II Narcotic?
It is a Class III Narcotic.
