Funke, Gerard J. Tortora 2,105 solutions How do proteins enter the endoplasmic reticulum?Proteins are fed into the ER during translation if they have an amino sequence called a signal peptide. In general, proteins bound for organelles in the endomembrane system (such as the ER, Golgi apparatus, and lysosome) or for the exterior of the cell must enter the ER at this stage.
What is the source of energy for protein translocation into the ER quizlet?(a) The source of energy for cotranslational translocation into the ER comes from guanosine triphosphate (GTP) which binds to a signal recognition particle (SRP) which dissociates SRP from its receptor which causes nascent polypeptide and ribosome to transfer to the ER membrane.
How proteins are transported?From the endoplasmic reticulum, proteins are transported in vesicles to the Golgi apparatus, where they are further processed and sorted for transport to lysosomes, the plasma membrane, or secretion from the cell.
How does the nuclear pore restrict the passage of large molecules that do not bear?How does the nuclear pore restrict the passage of large molecules that do not bear the correct nuclear localization signal? Nuclear pore proteins contain disordered segments that form a gel-like meshwork inside the pore.
