MHC II Molecules are Provided for Peptide Association Through

Question

MHC II molecules are provided for peptide association through:
A)The Golgi apparatus
B)Lysosomal activity
C)Proteasome digestion
D)Peroxisomal activity
E)None is a correct choice

Accepted Answer

MHC II molecules are provided for peptide association through the Golgi apparatus. The Golgi apparatus is a complex of flattened membranous sacs that modifies proteins and lipids. It is involved in the processing and packaging of proteins for secretion. MHC II molecules are synthesized in the endoplasmic reticulum and then transported to the Golgi apparatus, where they are loaded with peptides.
