y Bo Window Help Which of the following membranes would ha z Unit 2 Exam Which organelle is important for sorting proteins to secretory vesicles or to the lysosome? O Golgi apparatus O peroxisome O endosome smooth ER O rough ER 1 pts D Question 20 when a membrane protein is radioactively labeled during synthesis and followed through the various organelles in the secretory pathway, all the radioactivity is concentrated in the cis-Golgi apparatus six hours after the protein synthesis and never leaves this organelle. This suggests that the protein O will be exported to the plasma membrane. O has a mannose-6-phosphate tag. has a membrane-spanning domain length that equals the thickness of the cis-

Explanation / Answer

1. The answer is: rough ER

Rough endoplasmic reticulum is responsible for protein sorting.

2. The answer is: has a membrane spanning domain length that equals the thickness of the cis golgi membrane

The protein belongs to membrane of the cis - golgi.
