Answer 1

Sec61 is the correct answer.

Sec61 is the central component of the protein translocation apparatus of the endoplasmic reticulum (ER). It is an evolutionary conserved complex which serves both co- and post translational translocation. Sec61 often associates with Sec62 and Sec63 to form Sec61-Sec62-Sec63 complex which may perform post-translational protein translocation into the ER. BiP is the ER luminal heat shock protein 70 and is required for the translocation in a reconstituted system.
