Place the Class I Processing Pathway in the Correct Order

Place the class I processing pathway in the correct order:

A) Peptides exported from the ER by TAP > peptides are digested by the proteasome > peptides are loaded onto class I > class I is exported to the cell surface
B) Proteins are digested by the proteasome > peptides are imported into the ER by TAP > peptides are loaded onto MHC class I > class I is exported to the cell surface
C) MHC class I moves from the cell surface to the lysosome by endocytosis > class I bound peptides are replaced with antigenic peptides in the lysosome > class I returns to the cell surface
D) Proteins are degraded by TAP > peptides are imported into the lysosome by the proteasome > peptide-MHC class I complexes are exported to the cell surface
E) MHC class I is transported to the ER by TAP > proteins in the ER are degraded into peptides by the proteasome > peptides bind MHC class I in the ER, and the complex is exported to the cell surface
