Presented by APCs as MHC-exogenous peptide complex
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.
Molecules, ions, and solvent molecules are typically found in a liquid.
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)
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.

Presented by APCs as MHC-exogenous peptide complex
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.
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.

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.
DRG Kleinlokomotive Class II was created in 1932.
