For 10 points, name this organelle into which nascent peptides enter from ribosomes.
A signaling pathway regulated by ATF6, PERK, and IRE1 is triggered when these structures are stressed. Thapsigargin specifically inhibits proteins in these structures, and one process that occurs in these structures is inhibited by tunicamycin. A protein system located within these structures is defunct in patients of Von Gierke's disease, and CHOP-induced apoptosis occurs when these structures experience UPR. The recognition of the N-X(S/T) ["N-X-S-slash-T"] sequon triggers another process in these structures, in which an oligosaccharide is transferred from dolichol to a peptide. Fatty acids are omega-oxidized in these organelles, in which the glucose 6-phosphatase system catalyzes the final steps of glycogenolysis and gluconeogenesis. The signal recognition particle pauses translation when it recognizes peptides bound for this organelle, which is the site of N-linked glycosylation. For 10 points, name this organelle into which nascent peptides enter from ribosomes.
