Nuclear envelope, ER, GA, Lysosome, Vesicles, Endosomes, PM (plasma membrane) Two types of Protein Synthesis ANS From free polyribosomes in cytosol From membrane-bound polyribosomes Polyribosome ANS a mRNA that has multiple ribosomes on it ...

four main pathways for protein sorting Correct Answer-1. cytosolic proteins are simply synthesized in the cytosol 2. proteins destined for peroxisomes, mitochondria, and chloroplasts and synthesized in the cytosol and transported across membranes into the organelles 3. proteins destined for the nucleus are synthesized in the cytosol and transported thru nuclear pores 4. proteins destined for the ER, Golgi, endosomes, plasma membrane, and secretion are synthesized on the ER by the secretory pa...

Question 1. For CD8+ T lymphocytes to recognize virally infected cells, the infected cells must — A. express functional HLA-DM molecules. B. express functional transporter associated with antigen presentation (TAP) 1 and 2 proteins. C. have trafficked through a germinal center. D. extinguish expression of its class I HLA molecules. correct answer: 1. Answer: B Explanation: In virus-infected cells, some viral proteins are degraded in the cellular proteasome, the major cellular protein de...
